“…These systems measured two or three components of linearly polarized light. Three cameras were used by Prosch et al 21 to obtain the first three Stokes-vector elements, and dual piezoelastic modulators were used by Stenflo and Povel 22 to measure the full-Stokes vector. Pezzaniti and Chipman 23,24 developed a Mueller matrix imaging polarimeter that has been used to examine optical elements in transmission and reflection.…”

Imaging polarimetry has emerged over the past three decades as a powerful tool to enhance the information available in a variety of remote sensing applications. We discuss the foundations of passive imaging polarimetry, the phenomenological reasons for designing a polarimetric sensor, and the primary architectures that have been exploited for developing imaging polarimeters. Considerations on imaging polarimeters such as calibration, optimization, and error performance are also discussed. We review many important sources and examples from the scientific literature.

“…Однако фотополяриметрия планет и подстилающей поверхности Земли из-за необходимости проведения вычислительных процедур не смогла получить ши-рокого распространения до момента появления циф-ровых методов обработки изображений [12]. Уже первые изображения поляризационных функциона-лов P и θ естественных и антропогенных объектов продемонстрировали исследователям качественные отличия изображений от привычных изображений двумерного распределения интенсивности, что сти-мулировало разработку телевизионных видеополя-риметрических устройств для лабораторных назем-ных [13,14] и самолетных измерений [5] и проведе-ние спектрополяриметрических исследований есте-ственных поверхностей [16].…”

“…Acquisition of polarimetric images is easy and feasible at the video rate. 34,[41][42][43][44] However, for demonstration purposes we photographed the scene on a Fuji Sensia 100 slide film, using a common SLR ͑singlelens-reflex͒ ͑Cannon EOS-5͒ camera. The slides were scanned by a Nikon LS2000 35-mm film scanner.…”

We present an approach for easily removing the effects of haze from passively acquired images. Our approach is based on the fact that usually the natural illuminating light scattered by atmospheric particles ͑airlight͒ is partially polarized. Optical filtering alone cannot remove the haze effects, except in restricted situations. Our method, however, stems from physics-based analysis that works under a wide range of atmospheric and viewing conditions, even if the polarization is low. The approach does not rely on specific scattering models such as Rayleigh scattering and does not rely on the knowledge of illumination directions. It can be used with as few as two images taken through a polarizer at different orientations. As a byproduct, the method yields a range map of the scene, which enables scene rendering as if imaged from different viewpoints. It also yields information about the atmospheric particles. We present experimental results of complete dehazing of outdoor scenes, in far-from-ideal conditions for polarization filtering. We obtain a great improvement of scene contrast and correction of color.
