Abstract

The invention provides a light source module. The light source module comprises a broadband light source, a collimating mirror, a dispersion unit and a digital micro-mirror array, wherein the collimating mirror, the dispersion unit and the digital micro-mirror array are successively arranged in the direction of propagation of illumination light beams emitted from the broadband light source; the illumination light beams emitted from the broadband light source enter the collimating mirror, and are collimated as parallel light beams with different wavelength; after the parallel light beams with different wavelength accepts light splitting of a dispersion unit, the parallel light beams with different wavelength enter different positions of the digital micro-mirror array; selective on-off can be performed on the parallel light beams with different wavelength by means of control of the deflection angle of the digital micro-mirror array; and then the parallel light beam with the selected specific wavelength is reflected. The invention also provides a line scanning multispectral imaging system. The line scanning multispectral imaging system selects the wavelength which is used for imaging through the digital micro-mirror array and filters most of the stray light so as to greatly improve the imaging speed. Besides, the line scanning multispectral imaging system is simple in composition, and is one to one correspondence in composition of the optical path, thus being simpler in control and usage.

Description

technical field [0001] The invention relates to the technical field of imaging in optics, in particular to a light source module and a line-scanning multispectral imaging system using the same. Background technique [0002] In recent years, because confocal technology can use slit or small hole filter to eliminate stray light in the imaging plane, the imaging resolution has been greatly improved, and confocal has the advantage of non-invasive inspection, it has become more and more research hotspot in the field of imaging . The traditional point scanning focus uses two galvanometers to scan at the same time, so that the light source illuminates every point of the object to be measured, and through its reflected light or fluorescence imaging, when the size of the object to be measured is larger, the time required for an image to scan is longer. Longer, the scanning speed requirements for the galvanometer also become higher. On this basis, line-scanning confocal imaging was ...
