利用平面平晶反射干涉制作低频全息光栅

Producing low-frequency holographic grating using plane flat crystal reflection

基于对光栅制作方法优缺点的分析,提出了利用平面平晶双光束干涉原理制作低频全息光栅的方案.在保证光栅质量的前提下,简化了原有全息光栅制作的光路,实验证明简化后的光路是可行的,所制得的全息光栅可用于光学教学实验.

Based on the analysis of the advantages and disadvantages of various methods to produce gratings,a method to produce low-frequency holographic grating was put forward using plane flat crystal reflection.To ensure the quality of the grating,the original light path was greatly simplified.The optical path was proved to be feasible by experiment,and the holographic grating obtained by this method could be used in optics experiment.
