Abstract
An optical apparatus adapted for insertion into the open end of a hand-gun barrel. A piezoelectric crystal produces an output signal in response to the hammer impact to cause an LED to be intermittently operated by an oscillator powered by batteries and produce pulses of light which are directed by a lens onto a target. The oscillator is also coupled to a counter which is reset by the crystal output and which disables a gate between oscillator and LED upon a first count and enables a gate connecting the counter reset to the crystal upon a second count.
Claims12
An apparatus for insertion in a gun barrel to produce pulses of light simultaing firing of the gun comprising:
- means for detecting vibrations produced by the hammer impact resulting from pulling the trigger and producing at least one electrical pulse in response thereto;
- a source of electrical energy connected to said detecting and producing means;
- and
- a light source connected to said detecting and producing means for producing said pulses in response to said electrical pulse.
A circuit for producing a burst of optical pulses, said circuit being adapted for fitting within the barrel of a gun, comprising:
- a piezo-electric crystal for producing an output signal in response to hammer impact of the gun;
- an oscillator for producing electrical pulses;
- an LED;
- means for applying said electrical pulses to said LED in response to said output signal so that said LED produces said optical pulses.
