Optical coating. An optical coating is one or more thin layers of material deposited on an optical component such as a lens, prism or mirror, which alters the way in which the optic reflects and transmits light. These coatings have become a key technology in the field of optics. One type of optical coating is an anti-reflective coating, which ...
Lens or camera fungus is the popular name for the infestation of optical devices such as lenses, low pass filter (OLPF) or the camera sensor, by fungal threads ( mycelium ). By germination of fungal spores and further spore formation, the infestation can spread beyond the initial fungal network. The sensor or glass surfaces of the lens are ...

An epipolar line is a function of the position of point X in the 3D space, i.e. as X varies, a set of epipolar lines is generated in both images. Since the 3D line OL – X passes through the optical center of the lens OL, the corresponding epipolar line in the right image must pass through the epipole eR (and correspondingly for epipolar lines ...
