PROCEDURE REGISTERING WEAK LIGHT SIGNALS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2002 - IPC

FIELD: astrophysics, biophysics, scintillation technology, light location. SUBSTANCE: procedure consists in measurement of time interval between start and center of gravity of single-electron pulse of photoemission unit. Current of single-electron pulses from output of photoemission unit is subjected to primary amplitude discrimination with upper and lower threshold levels, then to time selection securing transit of pulses with length exceeding certain threshold value. Pulses after time selection are subjected to norming by length. Device for implementation of procedure has photoemission unit, broadband amplifier, timer, pulse counter, decision- making unit, control unit and amplitude discriminator, time selector and pulse former connected in series. Another variant of device has photoemission unit with multichannel multiplying system, focusing-deflecting system, power supply unit, multitap delay line, matching resistors, broadband amplifier, sweep unit, clock pulse generator, pulse counter, multiplier, pulse former, gating unit, decision-making unit. Device is supplemented with amplitude discriminator with upper and lower threshold levels, time selector and first pulse former connected in series. Technical result of invention lies in increase by 18% of precision of registration of light flux and expansion of dynamic measurement range. EFFECT: increased registration precision of light flux and expanded dynamic measurement range. 3 cl, 22 dwg
