Equipment for simulated shooting

Hand held epuipment for simulating the shooting of a weapon, said equipment comprising

• a projector,
• a target,
• means for generating a beam of electromagnetic radiation and projecting said beam towards said target in response to operation of said trigger, and
• receiver means for sensing incidence of said beam on said target and signalling a "hit";
• wherein
• (i) said means for generating a beam of electromagnetic radiation has a power no greater than 40 mW, is adapted to generate a modulated beam, and includes means for transmitting said beam as a pulse of predetermined duration in response to each operation of said trigger;
• (ii) said target comprises a reflective surface operably situated to reflect said beam back along a path substantially parallel to said incident beam irrespective of the angle of incidence of the beam;
• and
• (iii) said receiver comprises the following components operable in series, an optical band pass filter, a photodetector, an amplifier for amplifying the signal received at said photodetector, a synchronous demodulator for excluding all but signals of substantially the same frequency and phase as said emitted beam, an electrical gate, means for detecting the operation of said trigger, and a timer activated by said means for detecting the operation of said trigger and connected to operate said electrical gate after a predetermined time, signals being forwarded to said "hit" indicator only when said gate is open;
• said equipment further comprising optical means resiliently mounted in the path of said beam and capable of responding automatically to movement of said projection immediately before firing with movement of said optical means to direct said beam behind the aim of said projector to account for the difference in speed of travel of said radiation and the projectile that it is to simulate, said resilience acting to return said optical means to its original position after said projector is still.
