本論文在實現一雷射測距儀,所採用的方法為相位法(即是對雷射光進行
光強度的調制). 雷射測距儀可以分為兩個部份:第一部份是光學部份,此
部份由中山科學研究院雷射物理 組提供,第二部份為電子訊號處理系統的
實作,電路含主控振盪器,本地振盪器,混頻器, 濾波器,自動增益控制電
路,相位計,測尺銜接電路及顯示電路.所完成的雷射測距儀之 測量結果
其變動率(resolution)誤差在 2mm 之內,可測距離為 50m.

This paper presents a laser range finder. The method of finding
range we used is beam modulation. This laser range finder can be
divided into two parts. First part is the optical system, which
is provided by CHUNG-SHAN INSTITUTE OF SCIENCE & TECHNOLOGY. The
second part is the electronic signal-processing system, which
contains oscillators, mixers, filters, automatic gain control
circuit, phase meter, and monitorial circuit. The resolution of
this laser range finder is in 2mm. The measured range of the
laser finder is within 50m.
