This is the Swiss Army Knife of imaging, the unit is more capable than a standard camera because the unit has access to 4 separate imagers, 3 of which can be filtered. The 4th imager is a FLIR lepton camera for thermal imaging. Not only can the device be used for multispectral imaging, the cluster of cameras forms a synthetic aperture which allows for the ability to see a target around occlusions. The potential for this unit is endless and the fact that it can be 3D printed and assembled using readily available and cheap parts allows otherwise expensive technology into the hands of the layman.
All components can be manufactured on a Makerbot. Preferably using ABS plastic. All components are screwed together using #6-32 screws. For more information please refer to: https://hackaday.io/project/6730-synthetic-aperture-multispectral-imager
