The latest and greatest version of the DOLPi whitepaper is now available for download in pdf format at: http://www.diyphysics.com/wp-content/uploads/2015/09/DOLPi_Polarimetric_Camera_D_Prutchi_2015_v2.pdf

This 80-page paper presents the development and construction of two low-cost polarimetric cameras based on the Raspberry Pi 2.“DOLPi-MECH” is a filter-wheel-type camera capable of performing full Stokes analysis, while the electro-optic based “DOLPi” camera performs full linear polarimetric analysis at higher frame rate. Complete Python code for polarimetric imaging is presented. Various applications for the cameras are described, especially its use for locating mines and unexploded ordinance in humanitarian demining operations.
