The optical-rotation-encoded snapshot multispectral imager combines an optical rotator and polarizer with a color polarization camera, allowing up to 12 band images to be reconstructed in a single snapshot. This approach provides a compact system for spectral imaging but requires computational reconstruction in order to estimate scene spectra. After reviewing the system architecture, we show experimental results and discuss performance. This system can be used as a simple platform for testing ideas of how we should analyze computational systems: their robustness, accuracy, and reliability.
