LIGHT SIGNAL RECORDING DEVICE ( VARIANTS ) Russian patent published in 2003 - IPC

FIELD: photometry. SUBSTANCE: light signal recording device incorporates photoemission device, broadband amplifier, control unit, timer and unit making decision. Another variant of recording device has photoemission device with multichannel electron multiplication system, focusing-deflecting system, power supply unit, multitap delay line, matching resistors, broadband amplifier, clock pulse generator, multiplier, univibrator, gating unit, scanner, decision making unit. Common for both variants is presence of N amplitude discriminators, N time selectors, N pulse formers, N pulse counters and adder. Inputs of all N amplitude discriminators are tied up with output of broadband amplifier, output of j-th amplitude discriminator is linked through j-th time selector and j-th pulse former connected in series to counting input of j-th pulse counter which output is connected to j-th counting input of adder which output is connected to input of decision making unit. EFFECT: enhanced accuracy of recording of intensity of weak light signals, expanded dynamic range towards measurement of intensity of heavier luminous fluxes. 2 cl, 8 dwg
