<p>The equipment simulates the firing of one or more projectiles from a gun at a target such that a beam of electromagnetic radiation replaces the projectile trajectory. The equipment comprises a projector for projecting a modulated beam of electromagnetic radiation towards a target in response to the operation of a trigger. The target has a reflective surface operable to reflect the beam back along a oath substantially parallel to the incident beam irrespective of the angle of incidence of the beam. The reflected beam is detected by a receiver which includes means for signalling the reception of a reflected beam as a "hit".
<??>Optionally provision is made to cater for differences which may arise owing to the different nature of the radiation beam and the projectile which it is to simulate.
<??>The equipment may include a score unit comprising a signal processor and visual display means. The detection of a reflected beam is radiated to a detector connected to the signal processor and the "hit" is displayed on the visual display means as well or instead of indication at the receiver. </p> |
