ABSTRACT:
An infrared acquisition device is described which surveys a relatively large field of view in which an emissive target is likely to appear. An optical system focuses an image of the target onto a mosaic of separate detectors arranged in concentric fields and so arranged that the appearance of the target image on the outer or peripheral field will reposition the optical system so as to move the image onto the inner or central field. Chopper means are provided for modulating the signal for processing into servo control signals and also for discriminating against background radiation.
