Abstract
An optical system 10 comprises a light source 12 which may be either a point source or collimated and an arrangement 11,22 for directing a beam of light from the source 12 towards a boresighting arrangement 16 associated with an imaging lens 14 for imaging objects in object space 13 onto a detection surface 15. The boresighting arrangement 16 provides a marker on the surface 15 denoting the pointing direction 18 of the system 10 and is arranged so that the marker is of box-like pattern (17A, B 19A, B) closely centred on the pointing direction 18 so as to avoid obscuration of that part of the object image which is coincident with the pointing direction 18.
