Problems solved by technology

Moreover, for some samples with large undulations, such as stacked cell samples, the sample itself has unevenness, even if the array imaging system has reached the parfocal design, it cannot complete the alignment in a single imaging process. Clear imaging of such samples
It can be seen that due to the large size of the traditional microscope eyepiece body relative to the sample, and there is no adjustable focus microscopic microscope product or combination method suitable for this situation, in the existing technical solutions, this type of focusing problem has not been solved. good solution

Abstract

The invention relates to a microscopic imaging system. The microscopic imaging system comprises a plurality of unit microscopic imaging modules arranged according to a preset rule, and a data collection card connected with the plurality of unit microscopic imaging modules, wherein each unit microscopic imaging module comprises an adjustable lens group capable of independently adjusting focusing, and a photosensitive module corresponding to the adjustable lens group; the data collection card is provided with a plurality of image processing modules in one-to-one correspondence with the pluralityof unit microscopic imaging modules. Each image processing module independently controls the focusing of the corresponding adjustable lens group, and obtains the data of the corresponding photosensitive module. By implementing the invention, the consistency requirement of unit module assembly can be reduced, and the production efficiency of finished products is improved.

Description

technical field [0001] The invention relates to the technical field of optical imaging, and more specifically, to a microscopic imaging system. Background technique [0002] With the development of optical imaging technology, the application field of optical imaging module is more and more extensive, and there are more and more products in the field of ultra-macro imaging and microscopic imaging. With the application and development of artificial intelligence technology in the field of image processing and With the mass production of high-performance image processing hardware, microscopic imaging technology is developing in the direction of large field of view, high resolution, and high throughput. For example, in wafer inspection technology in the field of industrial inspection, and cervical screening technology in the field of cancer screening, it is usually necessary to image centimeter-level samples with sub-micron resolution. At the same time, with the development of m...
