Problems solved by technology

The device has a digital recording system for microscopic images of objects, but does not have a visual system for microscopic images of objects. It can carry out digital recording of microscopic images, but it is not suitable for visual dynamic observation of microscopic images, and because the device uses monochrome The laser light source limits the depth between adjacent sampling points

Abstract

The invention relates to a digital holographic microscopy measuring device. It includes a laser beam splitting system which is connected with a digital microscopic image register system via a holographic microscopy system, said digital holographic microscopy system comprises object light transmission path, reference light transmission path and digital holographic image register system , the output of holographic microscopy system is connected with a object microscopic image visual system. The invention can realize the configuration measurement and the deformation detection of transparent microscopic object, and monitor the shape change of transparent microscopic object, the visual and digital recording of the microscopic image are also realized. The device can realize the non-contacting gauge of transparent substance fine texture which is based on the digital holographic microscopy; the dynamic property is well, substance to be measured don't need preparation of fluorescence and section.

Description

technical field [0001] The invention relates to a microstructure measuring device, in particular to a microstructure for measuring transparent objects, such as living cells and phase substances. Background technique [0002] At present, the main instruments for measuring the microstructure of matter include confocal scanning microscope, non-scanning confocal microscope, scanning probe microscope and interference microscope. Confocal scanning microscopes currently have super-diffraction-limited high resolution, high imaging contrast, and tomographic imaging. Scanning speed is one of the main constraints, and the requirements for system accessories such as scanning implementation devices are high and complex. Although the confocal non-scanning microscope eliminates the complicated scanning process, it also requires multiple images, and its processing time is equal to the scanning time. The further improvement of its speed depends on the frame acquisition speed of the image acq...
