Researchers used 3D printing and low-cost parts to create an inexpensive hyperspectral imager that is light enough to use on drones. The visible-wavelength hyperspectral imager (HSI) weighs less than half a pound and, according to researchers, can be built for as little $700 (USD). In a recent paper the team provides directions for creating the HSI. Researchers used 3D printing to create hyperspectral imagers that are light enough to use on a drone. The imager is the small protrusion on the bottom of the drone's body.
