The Development of Laser Displacement Sensor using CCD&Optical triangulation technique

CCD 와 Optical triangulation Technique을 이용한 Laser Displacement Sensor 의 개발

Optical triangulation is one of the most common methods for acquiring range data. Using this method. We have developed a new type of Laser Displacement Sensor. We used Area CCD instead of linear CCD and PSD (Position Sensitive Detector). And we have developed the robust algorithm for increasing the accuracy and used USB instead of RS-232C for increasing speed. We present results that demonstrate the validity of our method using optical triangulation technique, Area CCD, and USB.
