摘要：
The development of a hyperspectral imager (HSI) made from commercial off-the-shelf (COTS) parts enables the use of hyperspectral imaging on smaller low-cost platforms such as cubesats, drones, or other autonomous vehicles. However, HSIs built from COTS parts often suffer from more pronounced optical distortions, such as 'smile' and 'keystone', due to the shifted balance between cost and image quality. In this proceeding, radiometric, spectral, and geometric calibrations of a COTS HSI are presented. Furthermore, the calibrations are used to develop a real-time software-based spectrogram correction. The corrections will enhance the capability of small, autonomous platforms in using hyperspectral imaging.
