Holographic Imaging Platform

Abstract

The invention discloses a holographic imaging platform, which includes a box body, an optical element, a laser, a holographic dry plate and an illuminance meter. , the box cover is the top layer of the upper cavity, the component socket template is the bottom layer of the upper cavity, the optical element is fixed above the component socket template, and the adjustment mechanism of the fixture is located below the component socket template; the lower cavity has an opening on one side And the box with the component socket template as the top surface, the opening is used to operate the adjustment mechanism of the fixture. The substantive effects of the present invention are: providing a dark and stable holographic imaging environment, the imaging space is separated from the adjustment space, avoiding the disturbance of holographic imaging when adjusting the optical elements, and improving the imaging quality; the optical path can be directly adjusted by naked eyes, Stimulate students' interest and effectively protect eyes from laser damage; precisely control exposure time.

Description

technical field [0001] The invention relates to the field of optical experiment devices, in particular to a holographic imaging platform. Background technique [0002] The principle of holography was proposed as early as the 1940s, but because it is difficult to find highly coherent object light and reference light, holography cannot be realized. The emergence of laser, because of its good coherence, holography has been practically applied. Now use a beam splitter to split the laser beam into two beams, the weaker one is used as reference light, and the other one is used as field light. Interference occurs when two beams of light converge at the same time. If the object light comes from the scattered light waves of an object, then the photosensitive plate can be developed and fixed after being exposed to light, and all the phase and amplitude information of the object light can be recorded. Obtain a hologram; when the object light needs to be reproduced, the hologram can ...
