The design of a wide-angle and wide spectral range pushbroom hyperspectral imager

We present the design of a compact, wide-angle pushbroom hyperspectral imager with a 42-deg wide field of view and a broadband response that covers the spectral range 450 to 2500 nm and provides a spectral sampling of 10 nm on SWIR and 5nm on VISNIR. The hyperspectral imager has finished the remote sensing experiment by emplaning on the YUN-12,and its performance meets the design parameters. The design is the high level technology and serves as an example for illustrating the design principles specific to this type of system.
