Mosaic filter has a highly integrated spectrophotometric function, which can greatly optimize the structure of the imaging spectrometer spectrometer system. When it is used as a spectral component in the imaging spectrometer, it can realize the miniaturization and lightweight of the imaging spectrometer.
The imaging spectrometer with the filter as the core component can work in video imaging mode, overcome the shortcomings of traditional imaging spectrometers which need to push the image, and greatly improve the efficiency of spectral imaging. Product applications: camouflage identification, precision agriculture, geological exploration, medical monitoring, etc.
Pixel level Mosaic filter, referring to the color filter RGB channel arrangement, multiple micrometer level spectral channels are arranged into a spectral period according to a certain law, and multiple spectral periods are arranged on the filter surface in a Mosaic way. The physical size of the filter can be determined according to the pixel size of the detector so that the spectral channel and detector pixel can be aligned one by one.
