METHOD AND DEVICE FOR ANALYZING AND SYNTHESIZING IMAGES Russian patent published in 1995 - IPC

FIELD: electro-optics. SUBSTANCE: two rasters disposed closely are formed simultaneously at subject plane by means of single analyzer, at short-time interruption of beam flow from optical channels of two-channel device, for example, IR imager. Radiation from the devices achieves the receiver along two parallel branches. Due to revolution of obturator, flow is modulated in one channel, and different signal spectra are formed in two channels. These spectra are separated at output of each element by means of filters. After being amplified preliminary, the modulated spectrum is detected. After that both signals come two switch inputs of commutators, in which the corresponding switches are integrated into groups and have two outputs, which are connected with indicators through two video amplifiers. Image of two lines are joined onto the screen to form wide line, and wide raster is formed as a result of action of deflecting system. EFFECT: improved quality of information; improved efficiency. 3 cl, 10 cl, 6 dwg
