Abstract

The invention discloses an imaging system and an imaging method for differentiating a fluorescent radiation spectral image from a reflective spectral image. The imaging system comprises an objective lens, a first raster, a first convex lens, a second convex lens, a mask, a third convex lens and an optical sensor. Fluorescent light which is radiated from a scene and reflective light successively pass through the objective lens, the first raster, the first convex lens, the second convex lens, the mask and the third convex lens and arrive at the optical sensor. According to the imaging system and the imaging method, two sets of high spectral images with different characteristics can be recovered in coding images which are captured after two times of exposure, and analysis on a dynamic scene can be realized. According to the imaging system and the imaging method, combined coding of spatial dimension and spectrum dimension is used, and sacrifice in high spectral imaging in time dimension and space dimension are overcome. A result which is recovered through the imaging system and the imaging method has high robustness to noise.

Description

【Technical field】 [0001] The invention relates to an imaging system and method for distinguishing fluorescent radiation spectrum images and reflection spectrum images. 【Background technique】 [0002] Hyperspectral imaging is a technology about obtaining dozens or even more spectral information of a single scene point. The hyperspectral image set obtained by hyperspectral imaging can be regarded as three-dimensional data composed of spatial dimension (two dimensions) and spectral dimension (one dimension). Hyperspectral imaging technology is often used in remote sensing photography, biomedical analysis, material analysis and other fields. Relying on these applications, many hyperspectral imaging methods have been proposed. The traditional hyperspectral imaging method sacrifices the time dimension to meet the requirements of the spectral dimension, and uses time-sequential spectral scanning to complete imaging. In order to overcome this disadvantage and realize hyperspectra...
