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.
