Hi! DOLPi is a low-cost polarization camera based on the Raspberry Pi.
Like intensity and color, polarization is another property of a light wave.
Humans cannot sense polarization, but many animals like cuttlefish and insects have polarization-sensitive vision that they use for navigation, finding water, and detecting transparent prey.
This is DOLPi – it is completely self-contained and easy to build. In spite of its simplicity, it holds truly awesome power for the development of brand new scientific and commercial applications!
