Abstract

The invention belongs to the technical field of biological fluorescence imaging, and provides a near-infrared two-region microscopic imaging system and method based on laser scanning, and the method comprises the steps: carrying out the beam deflection and beam combination of laser beams with different wavelengths, and obtaining combined light; shaping the combined light to obtain shaped light; phase-modulating the shaped light to generate a multi-focus illumination light field; relaying and two-dimensional scanning are carried out on the shaped light subjected to phase modulation, so that a multi-focus illumination light field is subjected to two-dimensional scanning on a focal plane of a microobjective, a sample is excited to emit a fluorescence signal of a near-infrared second-area wave band, and a near-infrared camera is used for detecting the fluorescence signal and imaging. According to the scheme, an optical path system is simple to integrate, and deeper imaging can be realized due to longer excitation wavelength; and the dye selection of the near-infrared second region is more flexible.

Description

technical field [0001] The invention belongs to the technical field of biological fluorescence imaging, in particular to a near-infrared second-region microscopic imaging system and method based on laser scanning. Background technique [0002] As an indispensable technical means in the field of biomedicine, biofluorescence imaging technology has been widely used, and it is a powerful tool to observe the morphology, structure and life phenomena of biological tissues. At present, the commonly used biofluorescence imaging technology is the laser scanning confocal microscope developed in the 1980s. It is characterized by the use of pinhole technology to eliminate the interference of light signals outside the focus on the image, thereby greatly improving the clarity of the image. Detail resolution with high axial contrast. Since the laser range used by the laser scanning confocal microscope is between 488nm and 647nm, it belongs to the visible light category, and biological tiss...
