Description
Two-dimensional PSD
S1880, S2044
Non-discrete position sensors utilizing photodiode surface resistance
PSD (position sensitive detector) is an optoelectronic position sensor utilizing photodiode surface resistance. Unlike discrete element detectors such as CCD, PSD provides continuous position data and features high position resolution and high-speed response.
