Hamamatsu Photonics 位置敏感測器( PSD),是利用光電二極體表面電阻而成的光電位置感測器。不像一般CCD , PSD提供連續的位置數據( X或Y坐標數據) ,具有高分辨率和高反應速度。
Hamamatsu Photonics Position sensitive detectors (PSD) are optoelectronic position sensors utilizing photodiode surface resistance. Unlike discrete element detectors such as CCD, PSD provides continuous position data (X or Y coordinate data) and features high position resolution and high-speed response.
