Abstract
A sensor assembly (10) includes first and second focusing mirrors (21, 22) which direct converging radiation to a tilted beam splitter (31) through an opening (23) provided in the first mirror. The beam splitter passes selected infrared radiation, which then passes through a lens system (33, 34, 41) to an infrared detector (16). The beam splitter reflects other radiation, which then passes through a different lens system (46, 56, 58, 61, 62, 67, 68, 69) to a second beam splitter (73). The second beam splitter passes laser light, which travels through a lens (77) to a laser light detector (18). The second beam splitter reflects near-infrared radiation, so that it travels to a further detector (17).
