How to choose a lens for a new eye

June 18, 2021 Comments Off on How to choose a lens for a new eye By admin

A new generation of optical surgical equipment is being developed to treat blindness.

A pair of high-tech lenses can be implanted into the eye to allow people with the disease to see in their left eye, using an artificial vision system developed by Cambridge University and the Oxford University School of Optometry.

The system uses an array of lasers to focus light onto a sensor in the eye, allowing the eye surgeon to see an image of the eye from the other eye.

The sensors used in the device include an array that can detect objects and detect movement in the eyes of people with blindness.

The technology can be used in people with vision loss and their eyes are normally misaligned.

“We’ve developed an array system that can sense objects in the field of vision of people who are blind and then we’ve created an artificial eye that can recognise that,” Professor Stephen Maitland, from the Oxford Optical Science Laboratory, told BBC News.

The team of scientists are currently working on an implant that can allow people who have lost their sight to see without a filter or glasses.

“In this case we’re able to use an artificial image in the left eye and a filter that is in the right eye,” said Dr Matt Levett, from Cambridge’s Optical Science Lab.

“It will be a truly amazing technology for people with this condition.”

“Our project is to find a way to treat this condition, to help people with visual loss to regain the ability to see,” Dr Leveitt added.

The researchers say the new technology could revolutionise the field.

“If you can see a computer screen or a video game screen in your right eye, but you can’t see the screen in the other one, it can be quite challenging to control it,” said Prof Maitlands.

“That’s where this new technology comes in.”

In addition to the new device, the Cambridge researchers are developing new tools to test the accuracy of the system.

“For the first time we’ve got a real-time software test system, where you can control the device, and we’ve now built a virtual reality simulator that allows you to test out the system,” Dr Maites said.

“You can see the test results from the left and from the right, it gives you a very good indication of the performance of the device.”

The research was funded by the European Research Council and the Cambridge Optical Society.

NASA: New laser instrument uses high-speed laser to scan for hidden organisms in deep ocean

June 17, 2021 Comments Off on NASA: New laser instrument uses high-speed laser to scan for hidden organisms in deep ocean By admin

NASA is developing a new laser instrument to detect hidden microbes beneath the oceans surface, according to the agency’s Chief Technology Officer for Optical, Optical Engineering, and Optics, Michael Smith.

The newly developed device is being developed for the Deep Ocean Lidar, or DELLO, mission.

The DELLA mission is NASA’s flagship ocean-going ocean research mission that will use lasers to survey the ocean floor for life and other organisms.

Smith, NASA’s DELLH, described the new device in a statement as a “fusion of technologies” that will be a “major contribution to our understanding of the deep ocean.”

The DEllH mission will be led by NASA’s Jet Propulsion Laboratory, Pasadena, California, and consists of three spacecraft: the DELLI (Deep-Diving Laser Instrument) and the DELE (Deep Low-Energy Laser) spacecraft, which is designed to survey deep ocean depths in excess of 3,000 feet (1,700 meters) below the surface.

The two DELLOs are designed to be deployed in tandem and will launch in 2020 and 2021 respectively.

The first two DEllOs are set to launch in 2021, followed by the first DELLM (Deep Ocean Lateral Imaging Module) spacecraft in 2022.

DELL-based sensors will be used to map ocean water depth and the presence of microbial life, and the new DELLL (Digital Optical Instrument) instrument will measure the optical properties of light emitted by living organisms.

A high-resolution infrared camera will be installed aboard the DEllM spacecraft to detect life, as well as other signs of life.

DEllL will use a new, more powerful version of the optical instrument called DELLS (Deep Depth Optical Spectrograph).

Smith also told Space.com that the new instrument is the largest optical imaging system ever deployed.

“We’ve had the capability for many years now, and with the DEHL (Digital Low-Emission Laser Sensor) mission, we are finally starting to get the capability to do what we wanted to do with the previous mission, which was imaging and sensing of water,” Smith said.

“With the DEALS (Digital Ocean Segment Sensor) we are really getting the capability and capability to detect these very small, very transient features in the water.”

DELLN-based instruments, called DEllD (Digital Depth Depth Camera), will also measure ocean water density and its depth.

The new DElls mission will also use new infrared sensors for mapping the surface of the ocean.

The mission is currently planned to launch sometime in 2019, but NASA is expected to award a contract to build the spacecraft for a total cost of more than $10 billion.

“The DELL spacecraft is a significant advancement for NASA, but we’re not just building a space telescope,” Smith added.

NASA has previously announced that DELLD will study the seafloor under the surface using high-power infrared lasers. “

I think the DEELS mission is the single most important thing to happen to the ocean in the last 20 years, and I think it will be the most important mission ever launched.”

NASA has previously announced that DELLD will study the seafloor under the surface using high-power infrared lasers.

This new laser-based imaging mission is designed and developed at JPL, in the United States, and is funded by NASA, the Department of Energy, and several other agencies.

“This is a very exciting project for the Department and its partners,” NASA said in a release.

“As part of the DELS mission, DELL will also be able to search for microscopic life forms, including plankton, microscopic bacteria, and other life forms.”

DEll is also expected to detect signs of microbial activity.

“DELL will use optical instruments to measure the surface properties of water and detect microorganisms living on the seafloors surface, such as plankton and bacteria, as they search for microorganisms to sample,” NASA explained.

“Researchers will also study the spectra of light in the ocean, including light reflected from seaflouses, to gain insight into the ocean’s microbial life.”

NASA’s DeLL-related missions are already part of NASA’s Deep Ocean Science Program, which aims to conduct oceanographic and oceanographic mapping missions in the outer Solar System.

How to fix your broken lens

June 17, 2021 Comments Off on How to fix your broken lens By admin

New Scientist article New Zealand scientists have discovered a way to repair the lens of an optical instrument and it could be used to repair other optical devices as well.

The researchers believe they have developed a new kind of lens that can repair itself and could be useful in repairing optical devices that break down, or degrade over time.

The researchers developed a novel lens for an optically sensitive, light-detecting instrument called a coronagraph.

They made it using an ultra-light-sensitive semiconductor, which was then coated with a transparent polymer called polyimide.

The lens can be repaired by the polymer coating to allow light to pass through.

This can allow light from the outside of the instrument to pass inside and then be detected by the instrument.

The process of repairing a lens has been difficult because the materials and processes needed are so different.

The team used a method called optically reactive oxygen and nitrogen deposition to repair a lens made of copper oxide.

They were able to do this by adding a small amount of nickel to the copper oxide layer.

This made the copper oxidised, and the copper was used as a reactive oxygen gas, which would allow the researchers to form a film that would repair itself over time, the researchers said.

The next step is to improve the coating of the copper.

The team will be investigating this method for making a coating that can be used in the future.

How NASA’s Optical Survey Instrument helped confirm an asteroid was in orbit

June 17, 2021 Comments Off on How NASA’s Optical Survey Instrument helped confirm an asteroid was in orbit By admin

A new analysis of NASA’s optical survey instruments, which measure the light from asteroids in their orbits, has determined an asteroid is in a potentially habitable orbit around a star and could be habitable for at least one billion years.

The instrument’s analysis comes at a time when the Obama administration is looking for ways to expand NASA’s efforts to hunt for extraterrestrial life beyond Earth.

The new analysis found an asteroid could be in the habitable zone for as long as 1 billion years, or about a third of the planet’s current life span.

The asteroid is dubbed 2014 QE2, after the last known asteroid to pass near the star Sirius, which is also about 10,000 light years away.

The scientists used a NASA computer model to find the asteroid’s orbit and determine the orbits around it.

“We were able to figure out a pretty good orbit for the asteroid,” said Eric Eriksen, a researcher at the Southwest Research Institute and lead author of the study published in the journal Icarus.

“And, it’s not too bad.”

The asteroid’s trajectory, which takes it around the star in about one-third of its orbit, suggests the asteroid is close enough to be a planet.

In fact, the orbit of 2014 QEV2 is roughly as close as the orbits of Jupiter, Saturn, Uranus and Neptune.

The orbit of the asteroid around the stars Sirius and Eris has been difficult to pin down for decades.

NASA’s Hubble Space Telescope has searched for an object that could be the object since 1997.

In the last decade, the telescope has found evidence of a rocky body, a meteorite or possibly even an asteroid that was orbiting Earth in the outer solar system at the time it passed close enough for Hubble to capture its light.

But this study is the first to pinpoint the exact distance at which the object would be in orbit around the two stars, Erikser said.

The study also found that the asteroid could have a surface with liquid water and could potentially harbor life.

“The asteroid is a potentially good candidate for a habitable world,” Eriksman said.

The study, led by Erikssen and co-authors of a previous study, is based on the analysis of optical observations of the brightness of asteroids in the solar system from 2008 to 2012. “

But we’re going to have to see more evidence to confirm that it’s there.”

The study, led by Erikssen and co-authors of a previous study, is based on the analysis of optical observations of the brightness of asteroids in the solar system from 2008 to 2012.

The team analyzed the light emitted by the asteroids from the Kepler space telescope, which has a high sensitivity to light from distant stars.

That study found the brightness at which asteroids in our solar system are brightest is about 30 percent higher than that from other stars in the same part of the sky.

“So we can use the Kepler data to determine where in the sky they are,” Ersen said.

In 2012, astronomers made a series of observations that allowed them to determine the brightnesss of objects in the Milky Way, the Milky Holmes and other nearby galaxies.

The researchers compared that data with the data from Kepler to determine if there was a correlation between the brightness in the sun and the brightness for the asteroids.

“You could argue that the stars are the brightest stars in our galaxy, but that’s not really true,” Eriesen said, “and we’ve got to figure that out.”

That’s because the light in the galaxy is so different from that of the asteroids, making the light reflected by them much more likely to be absorbed by the atmosphere.

In addition, the light being reflected by an asteroid’s surface may be more than one-billionth of the light that is reflected by the stars.

Eriksing and his colleagues analyzed the data that was collected by the Hubble Space Observatory and the Wide Field Infrared Survey Explorer (WISE) satellite.

The telescope has also collected data from the Near Earth Object Search Telescope (NEOSAT), which is located on the moon, and the European Space Agency’s Planck satellite.

Both of those instruments have data that’s been taken with infrared telescopes.

“If we’re using data from these other two instruments, then we can be pretty confident that the data is not being affected by the brightness variations of the stars,” Eriksen said “It could be that the bright star that we’re looking at is actually a little brighter than the stars in that part of our galaxy.”

Eriks and his team did not use the latest data from Planck, which was launched in 2009, because the observations were so old.

The data for the Kepler observations is still being analyzed.

The authors did not calculate how many asteroids have a chance of meeting the criteria for being a planet or being in a habitable zone, but they estimate there are between 5,000 and 100,000.

The space agency said that the number of confirmed planets could grow to about 100, the number that is the most likely to meet the definition of being a world.

NASA also said that it expects the number to be
