Abstract: A line scanner for infrared radiation includes a rotatable unit including an optical system which transmits received radiation to an infrared detector during a scanning period determined by an aperture in the wall of a housing for the unit. A reference heat source in the form of a metallic plate is mounted on the interior wall of the housing peripherally of the rotatable unit so that the radiation produced thereby passes through the entire optical system during scanning by the system.

Abstract: A line scanner for infrared radiation includes a rotatable unit which houses two optical systems, each responsive to different ranges of wavelength. A deflector arrangement deflects the optical axes of these systems in two directions along the axis of rotation of the unit. The first optical system is connected to an infrared detector whereas the second system is used for orientation purposes either by (1) forming a visible image of the field to be scanned or (2) emitting light pulses in a predetermined direction for reference.
