Abstract:
A multi-sensor, electro-optical boresight mechanism comprising:an optical bench:a telescope, mounted to said optical bench, for receiving a target signal;first sensor means, mounted to said optical bench, for sensing a first frequency component of said target signal and generating an image therefrom;second sensor means, mounted to said optical bench, for sensing a second frequency component of said target signal and generating an image therefrom;boresight target generation means, mounted to said optical bench, for internally generating a boresight target signal along a first optical path; and optical means, mounted to said optical bench, for allowing said first and second means to sense said boresight target signal;corner reflector means disposed at an end of the first optical path opposite the boresight target generation means for retro-reflecting the boresight target signal;first beam splitter means interposed between the boresight target generation means and the corner reflector means along the first optical path for transmitting the boresight target signal towards the corner reflector means along the first optical path and reflecting said boresight target signal retro-reflected by said corner reflector means from a rear surface thereof along a second optical path;said first sensor means being disposed along the second optical path opposite the first beam splitter means; andsecond beam splitter means interposed between the first beam splitter means and the first sensor means along the second optical path for transmitting the first frequency component of the boresight target signal towards the first sensor means and reflecting the second frequency component of the boresight target signal therefrom along a third optical path;said second sensor means being disposed along the third optical path opposite the second beam splitter means.
