WebDefinition of Photodiode It is a semiconductor device having 2 terminals that produce current when exposed to light. Photodiode works on the principle of photoelectric effect thus convert light energy that falls on the surface of the material into electrical energy. As the intensity of incident radiation increases, the current through the device also increases. http://www.optique-ingenieur.org/en/courses/OPI_ang_M05_C06/co/Contenu_13.html
Visual phototransduction is the sensory transduction process of the visual system by which light is detected to yield nerve impulses in the rod cells and cone cells in the retina of the eye in humans and other vertebrates. It relies on the visual cycle, a sequence of biochemical reactions in which a molecule of retinal bound to opsin undergoes photoisomerization, initiates a cascade that signals detection of the photon, and is indirectly restored to its photosensitive isomer for reuse. Phototr…
