OPTOELECTRONIC DEVICE FOR REGISTRATION OF MOMENT OF BULLET CROSSING LIGHT SCREEN OF TARGET Russian patent published in 2010 - IPC F41J5/00 

FIELD: weapon and ammunition.

SUBSTANCE: device comprises radiator with units of power supply and optoelectronic converter with photodetector and photocurrent amplifier. Converter is equipped with photodiode, amplifier-filter, threshold device for reduction of measurement error as a result of nutation, generator of output signal into communication line with target and circuit of moment detection, when centre of bullet gravity crosses the screen. Photodiode is matched by spectral characteristics with radiator with thin flat ends-current contact jaws. Circuit for detection of moment of time, when bullet centre of gravity crosses the screen comprises quartz generator of pulses, trigger, circuit "AND", counter, digital comparator, central processor device and inverter.

EFFECT: reduction of radiator energy intensity, improved evenness of brightness along its length and reduced pulsation of light flow.
