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 ...

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 ...

A contact lens with microscopic line patterns tracks eye position with high precision using only a smartphone camera, ...

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

It’s not April 1. It’s still 2014. This isn’t a joke. Google just introduced a smart contact lens. For now it’s only a Google[x] experiment, but the idea involves a contact lens with a small wireless ...

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 ...

I think I'd rather prick my finger than wear a contact lens... I have someone in my immediate family who does it every day, and it's really not that bad. You have a spring loaded needle that does a ...

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 ...
