Summary: | The invention relates to an optical filtering optical path with dynamically adjustable band-stop wavelength based on a digital micro-reflector. The optical path is composed of a beam splitting system, a beam combining system and a filtering assembly. The light splitting system is used for splitting light from an original image of a target to form a dispersion spectrum so as to irradiate the digital micro-reflector; the filtering assembly is used for filtering some spectral bands in the dispersion spectrum from the light splitting system, and the wavelength range of the spectral bands is dynamically adjustable; and the beam combining system is used for receiving the filtered dispersion spectrum reflected by the filtering assembly, carrying out beam combining on the dispersion spectrum, and finally forming a recombined image on the detection surface. The working process of the whole system comprises the following steps: firstly, forming an original image from a target into a slit image through the light splitti |
