DOLPi_Mech: A Slower But Accurate Imaging Polarimeter

The image that the liquid-crystal-panel-based DOLPi takes at “45 degrees” is not strictly that, which is why I state in the paper: “Bossa Nova’s method is straightforward if laboratory optical-grade components are used. These are very expensive and out of reach for most private enthusiasts. However, I found through experimentation that a welding mask LCP

Hack-A-Day 2015 Prize DOLPi Submission Video

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
