Structure analysis and signal process to improve distance measuring accuracy of 3D laser scanner

3차원 레이저스캐너의 거리측정 정밀도 향상을 위한 시스템의 구조분석과 신호처리

This research presents both system structure analysis to improve performance of 3D laser scanner, which has time of flight method, and scheme to minimize distance measurement errors during signal process. With the help of reference source, we minimized the instability of electronic signal processing time and possibility of distance measurement errors. Furthermore, it helps easy alignment and accuracy of system by using fiber delay line and coupler.
