Title Proper : FULL SKY IMAGING POLARIMETRY FOR INITIAL POLARIZED MODTRAN VALIDATION
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : Although military studies of the last ten years have shown that visible polarimetrysupplies supplemental surveillance information, the polarimetric signatures of ground-based objects greatly depend on the illuminating skylight polarization. The polarizationof a pure molecular atmosphere is easily modeled. but aerosols and clouds modify clear-sky polarization substantially. The Air Force has developed a polarimetric atmosphericradiative transfer model (MODTRAN-P) to simulate atmospheric effects. To assistMODTRAN-P code validation, a full-sky visible polarimeter has been developed usingliquid crystal variable retarders (LCVRs). Unique calibration issues of LCVR instrumentsare addressed. A fisheye lens can be exchanged for a telephoto lens to provide systemflexibility. This allows comparison between changing sky and changing target.
