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 ...

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

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 ...

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 ...
