A Hyperspectral Imaging Spectrometer You Can Make

Hyperspectral imaging spectrometers are used to study the biophysical features of the Earth's surface, and have many applications in agriculture, and water quality monitoring to name a few. Despite how powerful this technology is, commercial hyperspectral imagers (HSI) can be unaffordable. To tackle this, we have developed an open source initiative called OpenHSI that aims to lower the barriers, and hence make hyperspectral technology accessible to a wider audience who can then apply it in exciting new applications. Our camera relies only on commercial-off-the-shelf components and 3D printing. We calibrated and validated the hyperspectral imager's performance after deployment on a drone and we achieved high spatial resolution and spectral resolution in the 400-820 nm range. In this session, we demonstrate the sensor and supporting software in action, and describe how you can make and calibrate one of these hyperspectral cameras as well.
