We present a compact, low-cost and portable multi-spectral imaging setup. The system is built over the open-source hardware and software platform.
The image sensors used were Red Green Blue (RGB), NoIR (RGB-IR) micro-camera controlled by a Raspberry Pi board mounted with different filters over a multiplexer.
The design files, schematics, and the product images are released with the open hardware license for reuse.
Refer to the provided user manual - User-Guide-Building-Spectral-Block.pdf for using the design files.
