  IGF::OT::IGF OTHER FUNCTION - PICOMETRIX'S TIME-DOMAIN TERAHERTZ (TD-THZ) NON-DESTRUCTIVE EVALUATION (NDE) TECHNOLOGY COULD BE USED TO INSPECT SPACE FLIGHT STRUCTURES SUCH AS INFLATABLE SPACE HABITATS, THERMAL PROTECTION SYSTEMS (TUFI-TYPE TILES, SOFI TPS), FOR VOIDS, DISBONDS, AND DAMAGE SUCH AS TEARING AND MICRON-METEORITE IMPACT. THE CURRENT INSTRUMENTATION PARADIGM IS THAT A MULTI-PURPOSE TD-THZ CONTROL UNIT IS USED TO PROVIDE COMMON DRIVE, DATA ACQUISITION, AND ANALYSIS FUNCTIONALITY TO INTERCHANGEABLE SENSORS AND IMAGING WHICH CONNECT TO THE CONTROL UNIT WITH A FIBER-OPTIC/ELECTRICAL UMBILICAL. HOWEVER, THE CURRENT COTS CONTROL UNIT IS SUBSTANTIALLY LARGER AND HEAVIER THAN WOULD BE DESIRABLE FOR A SPACE-FLIGHT CAPABLE UNIT. IN PHASE II WE WILL CONSTRUCT A PROTOTYPE COMPACT TD-THZ CONTROL UNIT WITH A FIBER OPTICALLY COUPLED REMOTE COMPACT TD-THZ REFLECTION TOMOGRAPHY SENSOR BASED ON THE PHASE I DESIGNS. AT THE END OF A SUCCESSFUL PHASE II, AND TRANSITIONED INTO PHASE III, WE ENVISION THAT A HAND-HELD A OR B-SCAN NDE IMAGER COULD ATTACH TO A CONTROL UNIT, SUFFICIENTLY ROBUST FOR SPACEFLIGHT, NO LARGER THAN A SHOEBOX. IN PHASE II, IT SHOULD BE POSSIBLE TO REDUCE THE SIZE OF THE CONTROL UNIT TO APPROXIMATELY 1/3 OF THE CURRENT VALUES TO, FOR EXAMPLE, 14 IN. X 10 IN. X 4 IN. AND 15 POUNDS.

  IN THIS PHASE II PROJECT, WE PROPOSE TO DEVELOP, CONSTRUCT, AND DELIVER TO NASA A PROTOTYPE SINGLE-SIDED COMPUTED TOMOGRAPHY TIME-DOMAIN TERAHERTZ (SINGLE-SIDED CT TD-THZ) SCANNER ACCESSORY. THIS ACCESSORY WILL BE SUITABLE TO BE MOUNTED ONTO A NON-DESTRUCTIVE EVALUATION (NDE) IMAGING GANTRY FOR THE SINGLE-SIDED INSPECTION OF SPACECRAFT AND LAUNCH VEHICLE COMPOSITE STRUCTURES. THE SINGLE-SIDED CT TD-THZ SCANNER WILL BE AN ACCESSORY WHICH WORKS WITH EXISTING T-RAY 4000REG TD-THZ NDE IMAGING INSTRUMENTS OWNED BY NASA (AND OTHER AEROSPACE FIRMS). WE WILL ALSO DEVELOP, AND DELIVER A SOFTWARE PACKAGE WHICH EMPLOYS THE MODEL-BASED IMAGE RECONSTRUCTION (MBIR) METHODS. THE MBIR METHOD ALLOWS THE RECONSTRUCTION OF 2D SLICES IN DEPTH FROM THE DATA ACQUIRED BY THE SINGLE-SIDED CT TD-THZ SCANNER. THESE 2D SLICES CAN THEN BE STACKED LATERALLY TO GENERATE 3D IMAGES OF SUB-SURFACE STRUCTURES, FEATURES AND DEFECTS. TIME-DOMAIN TERAHERTZ IMAGING IN THE 0.1 TO 3 THZ SPECTRAL RANGE IS CURRENTLY BEING USED TO CHARACTERIZE DEFECTS IN SPACE SHUTTLE INSULATION AND RELATED MATERIALS. THE PROPOSED PROJECT WILL LARGELY BE CONFIGURED FROM STANDARD PICOMETRIX THZ SUB-COMPONENTS, BUT INCORPORATE MEASUREMENTS OF THE SCATTERED THZ FIELDS, ENABLING FULL 3D REFLECTION-MODE RECONSTRUCTION OF NON-METALLIC MATERIALS WHERE ONLY ONE SIDE IS ACCESSIBLE.
