Near infra-red black silicon pushbroom hyperspectral imager

This study introduces a 3D-printed near infra-red hyperspectral imager (NIR HSI). A prototype payload design for the next-generation CubeSat satellite missions is presented. The detector is a recent Black Silicon CMOS sensor. The assembled instrument is calibrated and tested to show it is capable of high framerate pushbroom acquisition at 90 frames per second. The spectral bandpass is 3.33 nm and the field of view across the track is 11.4°. The high speed and sensitivity of the sensor, especially in the NIR region from 700-1000 nm, has made it possible to construct an unprecedented spectral imager for future drone and satellite missions.
