摘　　要：基于传统的双光束干涉原理设计了全息记录装置．该装置的主要部分由固定干涉臂、可调干涉臂以及角度调节装置组成，通过转动可调干涉臂，能够改变双光束干涉的夹角，同时可由角度调节装置的圆台刻度读出两干涉光束的夹角．圆台可测量的角度范围为45°～180°．全息实验得到的两干涉光束的光斑大小接近，直径约1．50cm．满足实验要求．In order to conveniently adjust the angle of holographic recording in the holographic ex- periment and control it precisely, a holographic recording device was designed based on double beam interference. The device mainly included a fixed arm, a movable arm and an angle adjustment device. The interference angle could be easily changed by rotating the movable arm. At the same time, the value of the angle could be directly read from the scale on the circular platform of the angle adjustment device. The measurable angle ranged from 45° to 180°. The beam spot size was 1.50 cm each, which could satisfy the requirement of the experiment.
