the polarized light is used in polarization imaging and detection in complex
environment, turbid atmosphere under the harsh conditions. Polarized light in the
transmission process is affected by smoke composition, the uneven distribution of
concentration, particle shape,particle refractive index and other aspects of the causes of
polarized light transmission, and the degree of polarization and polarization parameters
change. The polarized light research is single on theory study, the experiment equipment
simulating environment is not conducive to the transmission characteristics of quantitative
study of polarized light in smoke environment. This paper from the research and simulation
of smoke device, the device uesd the temperature and humidity adjusting device to control
the generation of water mist, to simulate the natural environment in the haze environment,
and use of particle size instrument and concentration detection device real-time monitoring
test . Polarized light transmission characteristics in the test program and its influencing
factors, which can provide reference of polarized light for the transmission characteristics.
the polarized light in the atmosphere, water and human tissue is more application. For
polarized light in turbid medium of different integrated transmission characteristics, this paper adopts the
mie scattering theory polarized light scattering method research in turbid medium, the transmission
characteristics of polarized light in turbid medium is given in the model, the change law of polarization
light intensity change. Finally based on the coherent polarization theory, USES the cross spectral density
partially coherent light polarization characteristics of transmission in the transmission process changes to
make predictions.
Polarization imaging detection technology in addition to the traditional imaging information,
also can get polarization multi-dimensional information, thus improve the probability of target
detection and recognition.Image fusion in turbid medium target polarization image research, is helpful
to obtain high quality images. Based on visible light wavelength of light wavelength of laser
polarization imaging, through the rotation Angle of polaroid get corresponding linear polarized light
intensity, respectively to obtain the concentration range from 5% to 10% of turbid medium target
stocks of polarization parameters, introduces the processing of image fusion technology, main research
on access to the polarization of the image by using different polarization image fusion methods for
image processing, discusses several kinds of turbid medium has superior performance of polarization
image fusion method, and gives the treatment effect and analysis of data tables. Then use pixel level,
feature level and decision level fusion algorithm on three levels of information fusion, DOLP
polarization image fusion, the results show that: with the increase of the polarization Angle,
polarization image will be more and more fuzzy, quality worse and worse. Than a single fused image
contrast of the image be improved obviously, the finally analysis on reasons of the increase the image
contrast and polarized light.
