Abstract

The present disclosure discloses a multi-spectral image acquisition device. The multi-spectral image acquisition device includes: a casing, a light source, a storage board, and an image collection hole, wherein: the light source and the storage board are located in the space formed by the housing; the light source is placed in The bottom of the housing is used to generate irradiation light; the object board is placed in the middle of the housing to carry the object to be detected; the object board is provided with an irradiation hole for transmitting the irradiation light, and the object to be detected is placed above the irradiation hole so that the irradiation The light is irradiated onto the detected object; the end of the housing away from the light source is provided with an image acquisition hole for collecting the image formed after the irradiated light irradiates the detected object. The invention uses different light sources to produce different wavelengths to irradiate the detected object, and uses a multi-spectral camera to take photos of different wavelengths to obtain images of different spectra, thereby avoiding complex optical structures and reducing costs. Interference, to ensure that all light entering the camera passes through the detected object.

Description

technical field [0001] The disclosure relates to the technical field of analytical instruments, in particular to a transmission-type absorption multispectral image acquisition device. Background technique [0002] Multispectral imaging technology is widely used in military fields such as missile early warning, reconnaissance, ocean surveillance, guidance, military surveying and mapping, meteorological detection and other fields. It has also been widely used in a series of fields such as scientific experiments. Therefore, the acquisition of multispectral images becomes very important. [0003] In the prior art, the multi-spectral image acquisition device usually divides the incident full-band or wide-band optical signal into several narrow-band light beams by means of spectroscopic equipment, and then images them on the corresponding detectors respectively, so as to obtain different spectra. Band image. At present, spectroscopic equipment mainly adopts methods such as grat...
