摘要
介绍了基于激光三角测量法的微小位移量检测原理,并依据这个原理,设计了以一维PSD为检测元件,以FPGA为时序逻辑控制部件,以AT89S51单片机为运算核心的微小位移量检测系统。
In this paper, the test principle of small displacement is introduced based on laser triangulation technique. According to this principle, we design the test system of small displacement . One-dimensional PSD is the test component , FPGA is the control component of timer and logic, and AT89S51 is the operation core.
