“…Conventional hyperspectral imaging spectrometer acquires spectral data cube either by spectral scan or by spatial scan. In order to achieve spectral scan, researchers insert an acousto-optical tunable filter (AOTF) between the imaging lens and camera CMOS, so that they can get an image of an object in a certain spectral band [15][16][17][18] . The images acquired in each band is very clear, and post processing to obtain hyperspectral data cube is quite easy, simply stacking up images of different spectral bands.…”

We design and implement a compact and lightweight hyperspectral scanner. Based on this, a novel rotational hyperspectral scanner was demonstrated. Different from translational scanning, rotational scanning is a moveless and stable scanning method. We also designed a relevant image algorithm to reconstruct the image from an angular recorded hyperspectral data cube. The algorithm works well even with uncertain radial and tangential offset, which is caused by mechanical misalignment. The system shown a spectral resolution of 5 nm after calibration. Finally, spatial accuracy and spectral precision were discussed, based on some additional experiments.
