Dark current definition

WebA dark-current of 8 X 10^-5 pA is much smaller than 10 pA, which is the multiplied dark current level that just begins to significantly degrade the SNR at Ir = 10^-10 W/m^2. ... Almost by definition, amateurs are presently constrained to observations within our atmosphere. Notwithstanding the problems of infrared photodetector sensitivity ... 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…

Definition of dark_current - Chemistry Dictionary

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. WebMar 16, 2024 · I found this definition of collector dark current on a website: "When the phototransistor is placed in the dark and a voltage is applied from collector to emitter, a certain amount of current will flow. This current is called the dark current (ID). This current consists of the leakage current of the collector-base junction multiplied by the dc ...
