Research on the shortwave infrared hyperspectral imaging technology based on Integrated Stepwise filter

摘要

Highlights?Different spectral splitting methods are compared in this paper.?An ISF imaging spectrometer with 6stages of TDI is significantly higher than others.?An ISF hyperspectral imager prototype with 6stages of TDI was built.?A new method to derive the optimal blocking band curve of the ISF is provided.?A spectral calibration based on blackbody radiation with temperature scanning is proposed.AbstractSpace-borne hyperspectral imagery is an important tool for earth sciences and industrial applications. Higher spatial and spectral resolutions have been sought persistently, although this results in more power, larger volume and weight during a space-borne spectral imager design. For miniaturization of hyperspectral imager and optimization of spectral splitting methods, several methods are compared in this paper. S
