A semiconductor diode which, when exposed to light, generates a potential difference or changes its electrical resistance.
光电二极管
Example sentencesExamples
The receiver uses a photocell or photodiode to detect the light.
Semiconductor photodiodes offer high-sensitivity and low-noise operation, enabling them to detect very low light levels; attenuating filters must be used for high powers.
The image source may be replaced by an eyepiece, a CCD camera, a photodiode, a quad cell, or a fiber port.
The outputs of the sphere photodiodes and also the photodiodes monitoring the source laser power were sent to an oscilloscope.
The sensor consists of a silicon photodiode, with a pre-amp that gives enough signal for the voice channel of a small radio transmitter.
