【Abstract】 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°．更多还原
