FIELD: systems viewing distant objects in various sections of spectral range. SUBSTANCE: salient feature of invention lies in that photocells of matrix of charge-coupled devices are divided into linear or matrix groups. System of interference bands of standing light wave of coherent luminous radiation is projected on each group of isolated photocells by location of reflecting mirror between receiving lens and isolated groups of photocells of matrix of charged-coupled devices. Reflecting mirror partially transmits luminous radiation. Registration of system of interference bands of standing light wave in each isolated group of photocells is accomplished in signal of spatial frequency. Electric signals isolated in each group are fed to monitor. Viewing of objects with use of laser brightening is implemented with the aid of facility including transmission channel incorporating laser and optical system that forms laser beam, reception channel incorporating optically coupled receiving lens, matrix of charge- coupled devices, thin partially transmitting layer, reflecting mirror which partially transmits luminous radiation, data processing unit, spectrum analyzer and monitor. EFFECT: enhanced efficiency of detection of object in turbid medium. 6 cl, 2 dwg |
