摘　　要：通过光栅制备及表征实验,将全息技术、分光计应用、光谱仪技术及应用和夫琅禾费衍射等实验有机结合成光学模块体系.搭建了三角形和马赫-曾德尔干涉光路,制作了光栅常量为6.624~182.4μm的一维和二维全息光栅.利用光纤光谱仪校准激光波长,用光学显微镜观察光栅结构,并用分光计准确测量光栅衍射角,通过夫琅禾费衍射仪测量光栅衍射的强度分布,系统分析了光栅特性.通过实验验证了干涉角φ>1.88°的条件下,实现全息光栅的可控制作.Through grating preparation and characterization experiments,holography technology,spectrometer application,spectrometer technology and application,Fraunhofer diffraction were organically combined into an optical module system.Triangular and Mach-Zehnder interference light paths were built.One and two-dimensional holographic gratings with grating constant of 6.624~182.4μm were manufactured.The laser wavelength was calibrated with a fiber spectrometer,the grating structure was observed with an optical microscope,and the diffraction angles of gratings were accurately measured with a spectrometer.Finally,the grating properties were systematically analyzed by measuring the intensity distribution of grating diffraction with a Fraunhofer diffractometer.In addition,it was confirmed experimentally that fabrication of the holographic grating could be realized for the case of the interference angle larger than 1.88°.
