Abstract

The invention discloses a microscopic imaging system that comprises an LED array including light with a plurality of wavelengths; an amplification device disposed on one side of the LED array; a diffraction grating disposed on one side of the amplification device and satisfying conditions that light with different wavelengths is refracted at different angles and that the light with the same wavelength can be refracted to the same angle; an imaging lens array and an acquisition device array that are arranged on one side of the diffraction grating, wherein the light of one wavelength is provided with an imaging lens and acquisition device group, and respective imaging lens and acquisition device groups are placed at different spatial positions so that the imaging lenses and the acquisition devices acquire light with corresponding wavelength; and a controller connected with the LED array and the acquisition device array so that the acquisition device array performs synchronous data acquisition while the LED array transforms an illumination mode. The microscopic imaging system can acquire multiple sample images at one time and greatly enhances an information transmission capability.

Description

technical field [0001] The invention relates to the technical field of microscopic imaging, in particular to a microscopic imaging system. Background technique [0002] In optical imaging, field of view and resolution have always been important indicators for evaluating the performance of imaging systems. But in a traditional optical system, the spatial bandwidth product (SBP) is limited (generally only a few million pixels), that is to say, it is impossible to obtain a wide field of view and high resolution in the imaging process of. At present, researchers are increasingly applying computational methods to optical imaging, realizing some optical imaging methods that can simultaneously obtain wide field of view and high resolution, and are increasingly used in biological research. The FPM (Fourier ptychograhicmicroscopy, frequency-domain collage microscopy) system is such a method, which can obtain a sample image of one billion pixels without mechanical scanning, which ca...
