摘要
对全息光栅的制作进行了理论分析，提出了制作大空频全息光栅的一种光路，并讨论了在普通光学实验室中制作各种全息光栅空频的具体方法与操作技术．这种技术光路简单、抗干扰性强、易操作，是制作全息光栅的一种适用性很强的方法．
The theoretical analysis of holographic gratings and making technique in gen-eral optical laboratory are presented in this paper. The making method of gratings with various space frequencies is diseussed. This pracitcal method is simple, antidisturbed, and easy to operate.
