Hyperspectral cameras aren’t commonplace items; they capture spectral data for each of their pixels. While commercial hyperspectral cameras often start in the tens of thousands of dollars, [anfractuosity] decided to make his own with the Waverider. To capture spectral data from every pixel location in the camera, [anfractuosity] first needed a way to collect that […]
