PSIM Advantages vs. Current Art • Current Art Polarimetry – Three classes –   Multiplex-in-time. e.g. rotating waveplate. •   PROBLEM: Misregistration-in-time. –   Multiplex-in-space. e.g. pixel masks. •   PROBLEM: Misregistration-in-space. –   Parallel. e.g. Beamsplitting w/ multiple analyzers. •   PROBLEM: Costly; alignment challenges. • Misregistration artifacts masquerade as polarization –   thereby defeating polarimetry’s appeal... –   or circumscribing it to temporally static or spatially uniform scenes.   • P-SIM Based Imaging SpectroPolarimetry Offers: –   Single snapshot multi-angle spectro-polarimetry –   Inherently registered spectrum and polarimetry –   Single CCD array –   Single beam optics –   Compact, rugged design P-SIM Enables Spectropolarimetry from Moving Optics Against Dynamic Scenes To PSIM Page Next Page
