Initial Application of An Open Source Hyperspectral Imaging Package (OpenHSI) for Do-It-Yourself Applications

Hyperspectral imaging spectrometers facilitate the study of the atmosphere and the biophysical properties of the Earths surface through spatial and spectral information. We present an Open-source Hyperspectral Imager (OpenHSI) initiative that brings together a pushbroom camera design using only commercial-off-the-shelf components and an extensible Python library to create spectrally calibrated reflectance datasets for publication. We built the hyperspectral imaging spectrometer to have high spatial and spectral resolution while trading off the available spectral region to the visible and near infrared for cost and size. In this work, we will demonstrate how practitioners can use the OpenHSI package to build and extend the camera for other applications and global missions. Furthermore, an accessible high-resolution hyperspectral camera can promote fine scale calibration and validation for other studies. The cameras performance was tested on Uncrewed Aerial Vehicle flights over a coastal region in Queensland, Australia and we present our results for this initial application. Future ventures with the OpenHSI camera design and code are also outlined.
