Abstract

In light transmission processing, light is effected by the fog/haze/smoke/dust environment usually. Thus reduce the capability of traditional photo-electric instrument in detection, transmission, imaging, because of the attenuation, scattering, absorbing of the atmosphere. Polarization transmission characteristics exist the potential possibility in observing object through fog and smoke, increasing observation distance, improve the environment adaptability of the photo-electric instrument. The influence of polarization transmission characteristics are analyzed by environment testing experiment in this paper, including light intensity, degree of polarization, angle of polarization etc. We research smoke and fog environment simulation technology, builds the process-controlled and parameter-measured indoor equipment to simulate smoke/fog environment. The experiments of the polarization characteristic are tested in two kinds of transmission mediums separately, which are water fog and oil smoke. The attenuation ratio is measured in different kinds of smoke concentrations. Polarization imaging experiment are tested separately in different kinds of illuminance lights, which are daylight lamp, LED lights and projector lights. The images are captured by imaging CCD with linearly polarized filters on degree 0, 60, 120. The polarization images on three directions are processed by image infuse algorithm. The experiment results are provided as the theory foundation and data reference in field of polarization transmission.
