PSD(Position Sensitive Detector)

E-mail contact

+886-2-8772-8910

PSDs detect position data of incident spot light. Monolithic, PSD can track very small positional changes over the photosensitive area. In contrast , discrete devices (CCDs) reslove distances PSDs provide higher position resolution with high-speed response and reliability.
Hamamatsu PSDs are fabricated using our own cutting-edge semiconductor process technology and have the following features:
 
FEATURES
●Excellent position resolution 
●Wide spectral response range
●High-speed response
●Simultaneously detects light level and center-of-gravity position of light spot.
●High reliability
 
 
PSDs measure position, angles, distortion, vibration, and lens refraction/reflection. Som product examples are laser displacement meters, optical remote control devices, distance sensors, optical switches, and camera shake correctors.
One-dimensional PSDs operate simply, comparing two output currents, which determine the position, Two-dimensional PSDs compare four output currents. Hamamatsu sells operating circuit boards for most PSDs.
