半导体激光器 自混合干涉 差动 位移测量 semiconductor laser self-mixing interference difference displacement measurement
摘要
提出了一种利用激光自混合干涉效应的差动式位移测量系统, 建立了系统的数学模型, 经仿真分析及实验验证表明: 和单激光管结构相比, 该系统位移分辨力提高了二倍, 达1/4光波波长, 且能大大减小光反馈强度引起的噪声及温度干扰。
Abstract
A differential displacement system using the self-mixing interference effect in a laser diode and its model is established. It is confirmed by computer simulating and experiment that the resolution of this system is two times of that of common single laser diode system. The intensity noise and temperature disturbance can be decreased greatly.
