A low-cost, do-it-yourself polarization camera
Cameras to detect light polarization could prove useful tools to spot everything from landmines to skin cancer, but the cameras out there can run in the tens of thousands of dollars.
David Prutchi—an enthusiastic DIYer with more than 20 years experience in the biomedical and medical instrument industries—captured this year’s Golden Mousetrap Gadget Freak of the Year award for Dolpi, a low-cost, RasPi-based polarization camera duo. The Dolpi is run off a standard Raspberry Pi single-board computer and dedicated 5 MP camera, according to a paper Prutchi has posted online about the device.
