My July column (“Calibrate camera coordinates and colors”) described techniques you can use to calibrate vision systems. In some cases, though, basic calibrations do not suffice. General-purpose ...

Cataracts remain a leading cause of visual impairment globally, necessitating precise and objective methods for assessing lens opacification. Recent advances in imaging, particularly through ...

Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their ...

Image: When a large nearby object, such as a galaxy, blocks a distant object, such as another galaxy, the light can detour around the blockage. But instead of taking a single path, light can bend ...

Using entire galaxies as lenses to look at other galaxies, researchers have a newly precise way to measure the size and age of the universe and how rapidly it is expanding. The measurement determines ...

Menlo Park, CA - Using entire galaxies as lenses to look at other galaxies, researchers have a newly precise way to measure the size and age of the universe and how rapidly it is expanding, on a par ...

OpTest systems are made up of custom optics, mechanics and electronics designed by Optikos engineers for advanced lens testing. Although other products on the market typically compromise by ...

This isn’t Google Glass in a contact lens, but it may just be Google’s first step in this direction. The company’s Google X lab just teased a smart contact lens on its blog that is meant to help ...

There’s no doubt that Google is becoming a full-fledged hardware company, but the latest Google X project is a lot different that tablets and smartphones — the company just announced that it’s ...

In 2014, Verily, Alphabet's life sciences subsidiary, teamed up with Alcon to develop a contact lens that could measure glucose levels in tears. The idea being that diabetics would have an easier, ...
