【Abstract】 In order to conveniently adjust the angle of holographic recording in the holographic experiment 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 1.50cm each,which could satisfy the requirement of the experiment.更多还原
