DEV OF AN INTERFEROMETRY/TOMOGRAPHY DATA REDUCTION SYSTEM

THE OBJECT OF THE RESEARCH IS TO PRODUCE AN INTERFEROGRAM REDUCTION SYSTEM WHICH WILL ALLOW THE COMPARISON AND INTEGRATION OF THREE DIMENSIONAL EXPERIMENTAL INTERFEROMETRIC DATA WITH THAT DERIVED FROM CFD CODES. INTERFEROMETRIC TECHNIQUES PROVIDE AN IMPORTANT SOURCE OF DATA IN AEROBALLISTIC RANGES; HOWEVER, THE AVAILABLE DATA REDUCTION AND INTERPRETATION METHODS ARE SEVERLY LIMITING IN TERMS OF THEIR ABILITY TO PROVIDE QUANTITATIVE INFORMATION. NEW AUTOMATED METHODS WILL BE DEVELOPED TO EXTRACT DATA FROM THE INTERFEROGRAMS FASTER AND MORE ACCURATELY AND TO DETERMINE THREE DIMENSIONAL QUANTITIES USING TOMOGRAPHY. THIS PROJECT WILL EVALUATE AVAILABLE ALGORITHMS, SOFTWARE AND HARDWARE AND WILL DEMONSTRATE THE SELECTED ALGORITHMS AND SOFTWARE THROUGH APPLICATION TO EXPERIMENTAL AND COMPUTER-GENERATED INTERFEROGRAMS RELEVANT TO AEROBALLISTICS. THE PHASE I EFFORT WILL BRING THE REQUIRED EXPERTISE IN AERODYNAMICS, HOLOGRAPHY, INTERFEROMETRY, TOMOGRAPHY, IMAGE PROCESSING, AND SOFTWARE DEVELOPMENT TO INTEGRATE INNOVATIVE DATA ACQUISITION SCHEMES WITH STATE OF THE ART DATA REDUCTION AND INTERPRETATION TECHNIQUES.
