Abstract
We present here a review of scientific theoretical researches performed during last five years at our Institute. Specific modern radiative transfer approaches and techniques. This is just that is meant as 'nontraditional' features. All these features formed a basis for evaluating somewhat surprising, but easily physically treated properties of images provided by active vision systems operating through a turbid medium. Specific topics are: (i) effects of fine backscattering pattern of coarse aerosols, such as fog or cloud droplets, on optical interference and the computational consequences of these effects; (ii) image contrast and ultimate visibility range of targets with different reflective properties and; in particular, possible improving of the visibility range of targets with different reflective properties and; in particular, possible improving of the visibility of a target as it is sinking into a turbid medium; (iii) imaging of non-Lambertian objects and peculiarities in their images; (iv) applications to assessing visibility quality of a car driver under poor weather conditions and some ways to optimize the visibility and to enhance the ultimate visibility range. We succeed in treating all these topics by rather simple analytical expressions requiring no sophisticated software to be dealt with.
