The Hyperspectral Single Pixel Imaging kit ONE-PIX is a hardware add-on to turn a spectrometer into a hyperspectral camera. Single pixel imaging is used to measure hypercubes in the visible region. It can be extended towards the near infrared region for agricultural applications, for instance. This modular kit can be used with different spectrometers. It is an ideal environment for getting started with hyperspectral imaging or single pixel imaging for indoor uses.
