全息光栅的可控制作及表征研究

Study on the Controllable Fabrication and Characterization of Holographic Grating

利用激光全息技术,通过马赫-曾德尔干涉光路制作了三种尺寸可控的一维光栅,选择了合适的实验参数制作了二维光栅。通过金相显微镜表征分析了一维光栅和二维光栅的显微组织,并精确测定了其光栅常数。

Using technology of laser holography,three kinds of controllable size one-dimensional grating were fabricated through Mach-Zehnder interference optical path,and two-dimensional grating was fabricated by choosing suitable experimental parameters.The microstructure of the grating was characterized by metallographic microscope,and the grating constant was determined accurately by metallographic microscope.
