Abstract

An electro-optical target acquisition system having a scanning mirror whichotates through a 360° azimuthal plane. The infrared (IR) signal of a target is reflected off a mirror and imaged by a lens through an optical derotator onto a linear array of IR detectors. The detectors produce a current proportional to the strength of the IR signal. The current of each detector channel is amplified and fed to a corresponding light emitting diode, LED, that is part of a linear array of diodes. This light is imaged by a coupling lens through an optical rotator onto the photosurface of an image intensifier tube. The light image of the LED's creates a corresponding electron image. The electron image is swept across the tube and impinges onto the tube's phosphor output plate and creates a light output. The light output is an intensified image of the LED's.
