Abstract:

In the present work, results of experimental investigations into the influence of turbid media (fog, smoke) on the quality of image of objects observed through them using active pulsed OES operating in the modes with constantly open receiver and controllable receiver (in the mode of selection of backscattered noise signal) are considered. It is experimentally confirmed that in the active pulsed OES with selection of backscattered noise signal, the quality of images of objects screened by turbid media can be almost 10 times higher than in the case of their operation with constantly open receiver. The image quality of objects in systems of vision with controllable reception is influenced not only by the optical length of the observation path but also by such characteristics as the average sizes of particles and their scattering and absorbing properties.

Keywords:

active pulsed OES with controllable receiver, frequency-contrast characteristics, mires, smoke, fog, laboratory experiments
