Abstract
An optical system including a beam of radiation, an optical sensing device and boresighting apparatus. The boresighting apparatus includes apparatus for sensing the location of the beam of radiation relative to a given beam reference location and for providing an output indication thereof and including computing apparatus receiving the output indication from the optical sensing device. The boresighting apparatus further includes apparatus for defining an aiming location in the optical sensing device which aiming location is related to the output indication and including apparatus for providing an optical system reference image at a predetermined spatial separation from the beam reference location which is sensible by the optical sensing device.
Claims14
An optical system comprising:
- a generator for generating a beam of radiation;
- an optical sensing device;
- and
- apparatus for boresighting the optical sensing device with the beam of radiation without there being required an optical interconnection between the generator and the optical sensing device and including:
- a beam location sensor operative to determine the location of the beam of radiation relative to a given beam reference location defined therein;
- and
- an aiming location fixed in position with respect to the beam location sensor and providing an optical system reference image at a predetermined spatial separation from the beam reference location, which separation is determined by virtue of said aiming locator being fixed in position with respect to the beam location sensor.
For use with any optical system including a generator for generating a beam of radiation and an optical sensing device:
- apparatus for boresighting the optical sensing device with the beam of radiation without there being required an optical interconnection between the generator and the optical sensing device and including:
- a beam location sensor operative to determine the location of the beam of radiation relative to a given beam reference location defined therein;
- and
- an aiming locator fixed in position with respect to the beam location sensor and providing an optical system reference image at a predetermined spatial separation from the beam reference location, which separation is determined by virtue of said aiming location being fixed in position with respect to the beam location sensor.
