Abstract:

THIS IS A PROPOSAL TO DEVELOP A HOLOGRAPHIC CAMERA THAT IS CAPABLE OF PRODUCTING A MOTION AND STRAIN DIAGNOSTICS PICTURE OF A LARGE SURFACE AT KILOMETER DISTANCES. THE INTENDED PURPOSE OF THE INSTRUMENT IS TO MONITOR SURFACES SUCH AS THE FACE OF A BUILDING, A BRIDGE FOUNDATION, A RETAINING WALL, OR A GEOLOGICAL STRUCTURE DURING INTERACTIONWITH REAL OR SIMULATED GEOLOGICAL OR METEOROLOGICAL FORCES. IN ORDINARY HOLOGRAPHY AN UNMODULATED REFERENCE WAVE THAT TRAVELS THE SAME DISTANCE AS THE OBJECT WAVE IS REQUIRED. THE PROPOSED RESEARCH WILL EXTEND HOLOGRAPHIC INTERFEROMETRYTO LARGE, DISTANT SURFACES BY DERIVING THE HOLOGRAPHIC REFERENCE WAVE FROM ONE OF THREE POSSIBLE SOURCES: FROM THE OBJECT WAVE; A METHOD KNOWN AS LOCAL REFERENCE WAVE HOLOGRAPHY; FROM AN OPTICAL DELAY LINE, OR FROM A GLINT ON THE OBJECT. THE RECORDING WILL BE FURTHER ENHANCED THROUGH THE USE OF CCD DETECTORS AND LIGHT AMPLIFIERS. STRAIN OR MOTION CONTOURS AND VIBRATIONAL MODE STRUCTURE CAN BE OBSERVED WITH RESOLUTIONS OF THE ORDER OF 0.3 MICROMETERS. THE DEVICE WILL EMPLOY DOUBLE PULSED HOLOGRAPHIC INTERFEROMETRY. THE RESEARCH WILL EMPLOY BOTH ANALYTICAL AND EXPERIMENTAL METHODS TO DETERMINE FEASIBILITY. THE RESEARCH WILL BE PERFORMED IN COOPERATION WITH THE UNIVERSITY OF CALIFORNIA, IRVINE, DEPARTMENT OF ENGINEERING.
