Experimental study of the compensation method for atmospheric attenuation
of probing laser radiation in active electro-optical systems
that provide an increase of target image contrast
Ivan Kozhedub Kharkiv National Air Force University Abstract.
The article deals with the experimental study of the compensation method for
atmospheric attenuation of laser radiation in active electro-optical remote sensing systems
with dynamic spectral processing of optical signals that provides an increase of target
image contrast. The compensation method for atmospheric attenuation of laser radiation in
active electro-optical systems consists in forming the spectral intensity of the probing
radiation not only on the basis of a priori data on the spectral features of the reflecting
surfaces of the target and the background, but also taking into account the spectral
transmittance of the optical radiation propagation medium. The experimental setup has
been developed, in which the source of radiation in the transmitting part of the electro-
optical system is three semiconductor lasers operating in the ranges of the red, green and
blue parts of the spectrum. Absorption light filters were used in the experiment as elements
simulating the spectral properties of the reflecting surfaces of the target and background.
The cuvettes with a liquid absorbing optical radiation were used as elements simulating
atmospheric attenuation.
Keywords:active electro-optical system, dynamic spectral processing, atmospheric
attenuation of radiation, semiconductor lasers.
