Non-discrete position sensor 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. PSD can be broadly divided into one-dimensional type and two-dimensional type. Two-dimensional type is further classified by structure into duolateral type and tetra-lateral type. The duo-lateral type has superior position detection ability such as smaller position detection error and high position resolution. Listed in this catalog are typical two-dimensional type PSDs.
