Pixel level (mosaic) multi-channel filter of 559-740nm

pixel-level mosaic filter, reference color filter RGB channel arrangement, will be a number of micro-, meter-level spectral channels in accordance with certain rules arranged into a spectral period, a number of spectral period to mosaic, the way arranged on the filter surface. The physical size of the filter can be customized according to the pixel size of the detector, so that the spectral channel can be aligned with the detector pixel one by one.

The filter has a highly integrated optical splitting function, which can greatly optimize the structure of the splitting system of the imaging spectrometer, and can be used as a splitting element in the imaging spectrometer, it can realize miniaturization and lightweighting of imaging spectrometer.

The imaging spectrometer based on this filter can work in video imaging mode, which overcomes the deficiency of push-broom imaging in traditional imaging spectrometer, and greatly improves the spectral imaging efficiency.

Applications: camouflage identification, precision agriculture, geological exploration, medical monitoring.
