High-speed structured light imaging system

Abstract

The invention relates to a high speed structure light imaging system. The high speed structure light imaging system comprises a pulse light signal generation device, a light circulator, a space dispersion device, a space light modulator and a light imaging device, wherein the pulse light signal generation device is used for generating a pulse light signal, the light circulator is used for adjusting a light path to make the pulse light signal incident from the pulse light signal generation device enter a first light path through the light circulator and return from the first light path to be incident into the light imaging device, the space dispersion device is arranged on the first light path and is used for expanding frequency spectrum of the pulse light signal incident from the light circular in the space, the space light modulator is arranged on the first light path and is used for modulating the light signal expanded in the space, and the light imaging device is used for utilizing the light signal modulated by the space light modulator to carry out imaging of a target object. The high speed structure light imaging system is advantaged in that the time for reconstructing a high resolution image is shortened, and a high speed structure light super-resolution imaging system is realized.

Description

technical field [0001] Embodiments of the present invention relate to a high-speed structured light imaging system. Background technique [0002] For many years, the resolution of wide-field / confocal fluorescence microscopy has been limited by the Abbe / Rayleigh limit of light, and structures below 200nm cannot be resolved. Effective tool. Current super-resolution imaging techniques mainly include super-resolution microscopy imaging methods based on single-molecule imaging, such as photoactivated localization microscopy (PALM) and stochastic optical reconstruction microscopy (STORM). ), and the method of improving the imaging resolution by modifying the point spread function of the light source, including stimulated emission depletion microscopy (stimulated emission deplet ion, STED) and saturated structure illumination microscopy (saturated structure illumination microscopy, SSIM). Compared with the three super-resolution imaging technologies, although the resolution of SI...
