Abstract : This patent describes the processing by an infrared television system of field of view radiant emission data such as spatial, radiometric and spectral information is facilitated by apparatus and operating methods that utilize a rotatable narrow band interference filter. The filter intercepts radiant emission from a selected scene at a 0 deg angle of incidence and at other selected angles of incidence up to 45 deg. Distinguishing between laser and graybody targets is accomplished by continuously rocking the filter between 0 and 45 deg as the television vidicon scanning rate or some harmonic thereof.
