Abstract:
1. An optical system for a tracking sensor, the optical system comprising: a beam splitter that splits the incoming radiation into a first beam set and a second beam set; a first reflector having a plurality of facets and first reflector aperture, said first reflector being in optical communication with said beam splitter; a second reflector having a plurality of facets second reflector aperture, said second reflector being in optical communication with said beam splitter; a first segmented beam deviator having at least one segment that deviates lines of sight of the first beam set into a first designated image blur according to a first deviation angle, said first segmented beam deviator having a predetermined number of segments and being in optical communication with said beam splitter and said first reflector; a second segmented beam deviator having at least one segment that deviates lines of sight of the second beam set into a second designated image blur according to a second deviation angle, said second segmented beam deviator also having the predetermined number of segments and being in optical communication with said beam splitter and said second reflector; a lens in optical communication with said first and second reflectors, said lens focusing said first and second beam sets onto a focal plane and the first and second reflectors are trihedral reflectors.
