Position Sensitive detector Developed

The research group including Pak Pyong Su, a head of lab the of Semiconductor Institute, developed entirely in our own way the position sensitive detector available for all kinds of precision devices such as an electronic scale, a range finding system, a bevel gauge, a vibrometer, and other displacement sensing elements and are now expanding its achievements.

The element has a non-linearity error of 0.1% and position sensitivity of 0.2 to 0.3㎛.
