LOW-LEVEL COLOR TV SYSTEM Russian patent published in 2001 - IPC

FIELD: color television systems, optoelectronic devices. SUBSTANCE: low-level color TV system includes receiving telescopic optics, beam-splitting optics in the form of two interference mirrors, three TV channels each incorporating electron-optical converter and reproductive lens, camera tube, video signal processing and amplification unit. Electron-optical converters of each channel have threshold sensitivity proportional to transmission factor of proper color and inversely proportional to square of aperture ratio of receiving focusing optics. Signals from outputs of camera tubes of all channels come to picture tube which constructs color image on its screen. EFFECT: enhanced light sensitivity of TV system. 1 cl, 1 dwg
