Description

The OSM910 Position Sensing Detector

(PSD) is a silicon photodiode designed

for use in distance or displacement

sensing applications. The PSD produces

an analog output that is directly

proportional to the position of a light spot

on the detector active area. The output

produced is independent of the light spot

intensity, profile, symmetry or size.
