1. A target system for a weapon effect simulation system, said target system comprising:

  • a retro-reflecting prism having at least three back surfaces arranged to retro-reflect an incident simulation beam and wherein at least one of the back surfaces comprises a first, selectively reflecting layer arranged to reflect a simulation beam of a predetermined optical wavelength range and being substantially transparent to optical wavelengths outside said range, wherein a second layer is mounted on the first layer, said second layer being arranged to receive beams transmitted through said first layer and said second layer being of a material having an index of refraction sufficiently high to avoid total internal reflection between said first and second layer within a predetermined range of incident angles.
