用多模半导体激光器实现动态定位的研究

Research on Dynamic Positioning Using a Multi-mode Diode Laser

提出了一种新的半导体激光定位技术。它利用多模半导体激光器的光谱分布引起的干涉条纹的强度分布来确定等光程差点。干涉仪体积小，信号处理简单，系统性能稳定，可以在大范围内捕捉零点。

A new positioning technology employing a diode laser is proposed in this paper.With the wide spectrum of a multi- mode diode laser, the intensity distribution of its interference fringes can be used to find the zero OPD point. The interferometer is small and available, the signal processing is simple, and the zero OPD point can be searched in a large range.
