We present the initial results of an imaging polarimeter operating at 632.8 nm that simultaneously analyzes four polarization states on a single detector array. In a single snap shot, the polarimeter has the ability to characterize the polarization of a scene by determining the complete Stokes vector. Images are processed to show Degree of Polarization (DOP), Degree of Linear Polarization (DOLP), Degree of Circular Polarization (DOCP), ellipticity and the angle of linear polarization. Our approach utilizes a monolithic analyzer that allows us to avoid issues usually associated with division of amplitude polarimeters such as jitter and tight tolerance requirements. We discuss our optical design, calibration procedure, and test data.© (2007) COPYRIGHT SPIE--The International Society for Optical Engineering.
