AI Technical Summary

Problems solved by technology

However, when the beam combiner is rotated, if the rotation angle is small, the off-axis holography in which the reconstructed image is completely separated may not be obtained, which affects the quality of the reconstructed image; if the rotation angle is large, part of the object light wave information may not be referenced. Recorded, thereby losing object information
In the prior art, the adjustment of the rotation angle of the beam combiner is done manually. This adjustment method has poor accuracy and affects the reproduction quality of the digital holographic image.

Embodiment Construction

[0017] Such as figure 1 As shown, the digital image recording experimental system of the present application includes a laser 1, a first half-wave plate 2, a polarizing beam splitter 3, a first reflector 4, a first beam expander collimator 5, a transparent object 6, and a beam combiner 7 (semi-transmissive and semi-reflective), CCD8, second beam expander collimating mirror 9, second reflector 10, electric zoom lens 11 and computer 12. The beam emitted by the laser is divided into the first beam and the second beam after passing through the polarizing beam splitter. The first beam enters the first beam expander and collimator after passing through the first reflector to form parallel light and irradiates a transparent object to form an object light wave. The light wave reaches the CCD target surface after passing through the beam combining mirror; the second beam after the polarization beam splitter and the second beam expander collimator form a plane light wave, and the plane ...

Abstract

The invention provides a microscopic image recording experiment system and image recording method. The change rule of a voltage applied to second electrodes distributed on a lower substrate in an electro-zooming lens is controlled, radiating spherical light waves are recorded, and an object image is recorded in a target surface of a CCD. Thus, voltage change is controlled, the radiating sphericallight waves of the needed spherical radius are obtained, and thus, an accurate microscopic image is obtained.

Description

technical field [0001] The application relates to a microscopic image recording experimental system and an image recording method, belonging to the field of optical teaching and scientific research experiments. Background technique [0002] The usual microscope is mainly obtained through the lens group, the microscopic image obtained in this way cannot be recorded and saved, and the details of the image will not be remembered very quickly after observation. With the continuous development of semiconductor technology and laser technology, a digital microscope has appeared at this stage, which can obtain the phase image of the imaged object while obtaining the intensity image of the imaged object, or it can obtain the three-dimensional image of the imaged object. And the obtained three-dimensional image can be permanently preserved. [0003] In existing digital holography, most off-axis holographic methods are used to obtain digital holographic images. The off-axis holographi...
