<p>The present optical system provides an all-reflective boresight transfer system. A reflective mechanism (10) receives and reflects energy from an incoming collimated beam to focus it upon a target surface. The target surface (16) absorbs and subsequently re-emits as a longer wavelength most of the energy and also reflects a small portion of the energy such that an exit beam (35) comprised of both the re-emitted and reflected energy is reflected through the reflecting mechanism and re-collimated by the reflecting mechanism. The exit beam has the same direction as the input beam except that it is deviated by 180 DEG and laterally offset from the input beam so that the exit beam may be used as a reference for determining or aligning the line of sight of other optical systems. <IMAGE></p> |
