METHOD OF OBJECT VIEWING WITH USE OF LASER ILLUMINATION AND FACILITY FOR ITS IMPLEMENTATION ( VARIANTS ) Russian patent published in 2003 - IPC

FIELD: systems viewing remote objects. SUBSTANCE: photocells of matrix of charge-coupled devices is divided into groups on to which system of interference bands of standing light wave is projected by way of placement of reflecting mirror between receiving lens and isolated groups of photocells which partially transmit luminous radiation and thin partially transmitting layer or periodic structure formed by thin-layer elements. System of interference bands in each group of photocells is recorded in the form of signals of spatial frequency, then image of object is generated on monitor. Proposed method of laser viewing is implemented by means of facility carrying transmission channel incorporating laser and optical system forming laser beam, receiving channel carrying optically coupled receiving lens, matrix of charge- coupled devices, thin partially transmitting layer or periodic structure formed by thin-layer elements, reflecting mirror that partially transmits luminous radiation, data processing unit, spectrum analyzer and monitor. According to another variant facility is supplemented with additional laser. EFFECT: enhanced efficiency of detection of mobile objects in scattering medium. 14 cl, 3 dwg
