CORRELATION-EXTREME HOMING COORDINATOR Russian patent published in 1998 - IPC

FIELD: optical location, information support systems for high-precision systems of guidance of location complexes on mobile objects. SUBSTANCE: proposed homing coordinator incorporates first Fourier objective 8, receiving optical system 1 and first spatial-time light modulator 2 put is series along first optical axis, first laser 9, first expander 10, beam splitter 11, shutter 12, second spatial-time light modulator 13, second Fourier objective 14, first photodetector 15 mounted in series along second optical axis, threshold unit 6, processing unit 20, control and synchronization unit 21. Homing coordinator is supplemented with third spatial-time light modulator 27, transfer objective 4, electrooptical modulator 26, polarization beam splitter 3, commutator 17, controlled threshold unit 19, peak detector 16, amplifier 18, selector 7, high-brightness TV camera 27a, second laser 22 and second expander 23. First spatial-time beam splitter is manufactured in the form of electron-optical converter ganged with spatial-time beam splitter based on electrooptical effect with the aid of fibre-optical faceplate which surface facing spatial-time beam splitter carries dichroic dielectric coat. EFFECT: increased precision under complex noise conditions. 3 cl, 4 dwg
