HOLOGRAPHIC PATTERN RECOGNITION FOR ARMS CONTROL

THE CONTRACTOR HAS PATENTED TECHNOLOGY FOR A UNIQUE PROCESS THAT DIRECTLY CONVERTS AN ACOUSTIC SIGNAL INTO A VISIBLE ONE IN REAL-TIME WITHOUT ELECTRONIC CIRCUITRY. THIS RELIES ON THE ACOUSTO-OPTICAL PROPERTIES OF A CONTINUOUS LAYER OF LIQUID CRYSTAL THIN FILM LAYER WHICH SERVES AS BOTH THE SENSOR AND THE DISPLAY. THE IMAGE CAN BE VIEWED DIRECTLY BY MEANS OF CCD CAMERA. HOLOGRAPHY PROVIDES FOR BOTH REDUNDANCY AND INCREASED RESOLUTION AS PROPAGATION THROUGH THE MEDIUM IS MADE BOTH EASIER AND MORE ACCURATE BY USING TWO WAVELENGTHS. IT UTILIZES TECHNIQUES SIMILAR TO OPTICAL HOLOGRAPHY WHERE AN ULTRASONIC WAVE ORIGINATING FROM AN OBJECT IS MADE TO INTERFERE WITH A REFERENCE WAVE PRODUCING AN INTERFERENCE PATTERN THAT IS A HOLOGRAM WHICH IS VIEWED 3-D DIMENSIONALLY ON THE DETECTION PANEL. THE CONTRACTOR WILL INVESTIGATE FEASIBILITY BY SYNTHESIZING AND TESTING LIQUID CRYSTAL MIXTURES SHOWN IN ITS PATENT. A POLARIZED BEAM OF LIGHT WILL BE USED TO MEASURE CHANGES IN DICHROISM BY MEASURING THE VARIATION OF ELLIPTICITY AS A FUNCTION OF PRESSURE.
