Abstract

The invention relates to the technical field of lens module imaging, and in particular relates to a multispectral imaging system which comprises an incident lens, a liquid crystal switch, a collimating lens, a first reflector, an imaging lens, a plane reflection type grating, a DMD spatial light modulator, a substrate, a first CIS image sensor and a second CIS image sensor. The incident lens, the liquid crystal switch, the collimating lens, the first reflector, the imaging lens, the plane reflection type grating and the first CIS image sensor are sequentially arranged from an object side to an imaging side, or the incident lens, the DMD spatial light modulator, the substrate, a second reflector and the second CIS image sensor are sequentially arranged from the object side to the imaging side. The incident lens and the imaging lens are convex lenses, and the second reflector is a concave mirror. A slit is etched on the substrate, and diffraction dispersion is carried out on incident light. The substrate and the second CIS image sensor are attached together, and the length of the second CIS image sensor is smaller than that of the substrate. A light source does not need to be specially modulated, and image information is greatly enriched.

Description

technical field [0001] The invention relates to the technical field of lens module imaging, in particular to a multispectral imaging system. Background technique [0002] The existing technology used to measure the spectrum of the light source is: a spectral sensor, which disperses the light through a grating and reads the light intensity of each wavelength through a linear CCD image sensor, and then calculates the spectral value, but this technology can only measure the light source. The point is imaged, but the image cannot be acquired. Commonly used in spectrometers. [0003] Existing techniques for obtaining multispectral images include: [0004] 1. Use different cameras to take different spectral images, and then superimpose and synthesize them to form a visible pseudo-color image. The disadvantage is that due to the difference in camera resolution and viewing angle, the image will have different deformations and the edges will not be aligned. Currently common in in...
