In this proposal, AlphaSense, Inc. (AI) and the Oklahoma State University (OKState) detail the development of a novel Cavity Enhanced Terahertz Absorption Spectrometer (CETAS). Key innovations of the proposed system include: a) the use of a small Whispering- Gallery- Mode (WGM) cavity to achieve very long pathlength; and b) the integration of the WGM cavity with the conventional pulsed and continu ...

UAVS (Unmanned Aircraft Vehicle System) integration with naval vessels is currently realized in limited form. This is largely due to the fact that the operational envelopes of these vehicles are based solely on at-sea flight testing. In addition to the complexities involved with at-sea flight testing, the unsteady nature of ship-airwakes and the use of automated UAV control software necessitates ...

In this proposal, AlphaSense, Inc. (AI) and the University of Michigan (UM) detail the development of a compact, portable, and low cost in-process weld defects detection system. Key innovations of the proposed system include: a) weld defects monitoring based on plasma emission characteristics; b) use the electron temperature of the plasma as an indicator of the weld quality, c) use multiple plasma ...

CONFIRMING THE ACCURAY OF LIFE-PROTECTING INDUSTRIAL HYGIENE TEST EQUIPMENT OR SIMULATING MILITARY ENVIRONMENTS OFTEN REQUIRES SOPHISTICATED AND CUMBERSOME TEST CHAMBERS DEPENDENT ON COMPLICATED CALCULATIONS. THE CALIBRATION OF SUCH TEST EQUIPMENT MAY BE EASILY COMPROMISED BY OPERATOR ERROR WHERE INVOLVED CALCULATIONS ARE USED AND COMPLICATED INTERCONNECTIONS AND VALVES ARE EMPLOYED. WE PROPOSE TO ...

AN INNOVATIVE CONCEPT FOR A TUNABLE IMAGING IR SPECTROMETER IS PROPOSED. THE DEVICE WILL CONSIST OF AN ACOUSTOOPTIC TUNABLE FILTER COUPLED TO A TWO-DIMENSIONAL FOCAL PLANE ARRAY DETECTOR. THIS IMAGING SPECTROMETER WILL COMBINE HIGH THROUGHPUT (APPROACHING 100%) WITH THE TUNABILITY AND HIGH RESOLUTION OF A GRATING SPECTROMETER, AND THE TWO-DIMENSIONAL IMAGING CAPABILITY OF AN INTERFERENCE FILTER. T ...

THE EFFECTIVENESS OF KINETIC ENERGY SPACE-BASED INTERCEPTOR MAY BE CONSIDERABLY ENHANCED BY ON-BOARD UV SENSORS CAPABLE OF DETECTING A POTENTIAL TARGET'S UV SIGNATURE. SUCH UV SENSORS MAY PLAY A CRITICAL ROLE IN TARGET IDENTIFICATION, TRACKING, SEEKING AND DISCRIMINATION AND MAY PROVE INSTRUMENTAL FOR EARLY WARNING OF ATTACK AND KILL DETERMINATION. SPACE-BASED APPLICATIONS, IN PARTICULAR, HAVE CRE ...

ACTIVATED STEEL FOIL FABRICATED INTO ELEMENTS TO BE PACKAGED AS EXPENDABLE DECOYS HAS SHOWN GOOD PERFORMANCE IN LOW IR SIGNATURE APPLICATIONS. THE PRESENT BATCH PRODUCTION PROCESS FOR THESE FOILS ENTAILS, IN PART, TWENTY HOURS OF FURNACE TREATMENT. A COMBINATION OF NINE SEPARATE OPERATIONS, LOW PRODUCTION RATES AND HIGH LABOR COSTS YIELDS A UNIT MANUFACTURING COST OF MORE THAN $250.00. WE PROPOSE ...

AN INNOVATIVE, COMPACT AND FAST DIRECTIONAL LASER SENSOR BASED ON THE LATEST ACHIEVEMENTS IN PHOTODETECTION TECHNOLOGY IS PROPOSED. THE LASER SENSING DEVICE USES A SPHERE LENS AS A DIRECTION IDENTIFIER, WITH A WIDE (+OR-90 DEG) FIELD OF VIEW. AN INCIDENT LASER BEAM IS FOCUSED BY THE SPHERE LENS ONTO A HEMISPHERICAL, AMORPHOUS SILICON, POSITION SENSITIVE DETECTOR LOCATED AT OR NEAR THE FOCAL SURFAC ...

Preliminary development of a noise audit model for vector sensor towed arrays will be performed and is focused on tasks related to validating an analytical model of a thin-line array. An in-house numerical code known as the duct transmission line (DTL) modeling tool will be adapted for specific application to towed arrays having periodic impedance discontinuities. Flow noise mitigation technique ...
