AT FREQUENCIES ABOVE 10 GHZ, CONVENTIONAL PHOTODIODES MUST SACRIFICE QUANTUM EFFICIENCY FOR SPEED SINCE THE THIN ACTIVE LAYERS REQUIRED DO NOT ABSORB ALL OF THE LIGHT PASSING THROUGH THEM. A WAVEGUIDE PHOTODIODE STRUCTURE ALLOWS ABSORPTION OVER A MUCH GREATER LENGTH ALONG THE ACTIVE LAYER THUS PROMISING BOTH SPEED AND EFFICIENCY. SUCH A PHOTODIODE REQUIRES A MORE SOPHISTICATED APPROACH FOR EFFICIE ...

IDENTIFICATION OF DISTANT, PASSIVE THREATS IN A COMBAT ENGAGEMENT WHERE LARGE CLUTTERED BACKGROUNDS ARE PRESENT IS OF MAJOR CONCERN TO INFRARED SENSOR SYSTEMS. THE IDENTIFICATION OF BOTH THREAT, FRIENDLY AND NEUTRAL, TARGETS IN A CLUTTERED SCENE ARE NECESSARY IN ORDER TO MAINTAIN THE ADDED EDGE NEEDED FOR SMART BATTLE MANAGEMENT AND SURVIVABILITY. IN MANY CASES THE DETECTION AND DECLARATION OF A D ...

IN THIS PROGRAM, THE FEASIBILITY OF PRODUCING A HOLOGRAPHIC LITHOGRAPHY MACHINE WILL BE INVESTIGATED. SUCH A MACHINE SHOULD HAVE HIGH RESOLUTION, LARGE FIELD MASKS, AND MINIMUM ABERRATION. BOTH THEORETICAL AND EXPERIMENTAL EFFORTS WILL BE MADE IN PHASE I TO FULLY DETERMINE THE LIMITS OF THIS APPROACH AND THE POSSIBILITY OF DESIGNING A PRACTICAL LITHOGRAPHY MACHINE FOR INTEGRATED CIRCUIT APPLICATIO ...

PHYSICAL OPTICS CORPORATION (POC) PROPOSES A FIBER OPTIC SENSOR-REPORTING SYSTEM FOR DETECTING KNOWN CHEMICAL AND BIOLOGICAL AGENTS AT REMOTE LOCATIONS. THE FIBER OPTIC SYSTEM IS ISNENSITIVE TO ELECTROMAGNETIC INTERFERENCE AND JAMMING WHICH WOUL RENDER A CONVENTIONAL ELECTRONIC OR RADIO TRANSMISSION SYSTEM MORE LIKELY TO FAIL. IT OFFERS VERY HIGH DATA CAPACITY AND CAN HANDLE A LARGE NUMBER OF SENS ...

PHYSICAL OPTICS CORPORATION (POC) PROPOSES A NOVEL 2-D SLM THAT IS: 1) ELECTRICALLY ADDRESSABLE; 2) PHASE DOMINANT; 3) POLARIZATION MODULATED AND; 4) HAS 3AND 4-STATE ARCHITECTURE. THE SUCCESSFUL DESIGN OF AN SLM THAT SIMULTANEOUSLY SATISFIES ALL OF THESE FEATURES IS ACHIEVABLE USING THREE EXISTING POC TECHNOLOGIES; 1) HIGH-EFFICIENCY VOLUME HOLOGRAPHY; 2) COHERENTLY-COUPLED TUNABLE HOLOGRAPHIC FA ...

ADVANCED FUZING MECHANISMS BASED ON HYDROSTATIC PRESSURE AND DECELERATION ARE NECESSARY TO SUCCESSFULLY DETONATE A WARHEAD AFTER PENETRATING THROUGH A MULTIPLE-LAYER MILITARY STRUCTURE. CONVENTIONAL FUZING MECHANISMS DETONATE ON IMPACT, WHICH ONLY DAMAGES THE OUTER MOST LAYERS OF A MILITARY STRUCTURE. PHYSICAL OPTICS CORPORATION PROPOSES THE USE OF AN INTRINSIC ELASTO-OPTIC FIBER OPTIC PRESSURE SE ...

THE ABILITY OF CREWMEMBERS TO OPERATE EFFECTIVELY AND SAFELY IS CONTIN UOUSLY BEING TESTED AS AEROSPACE VEHICLES ATTAIN FASTER SPEEDS, HIGHER ALTITUDES, AND HIGHER G ENVIRONMENTS. THE CREWMEMBERS' BREATHING APPARATUS OR MOLECULAR SIEVE OXYGEN GENERATING SYSTEM (MSOGS) IS OF PRIMARY IMPORTANCE. HOWEVER, NO SENSORS ARE AVAILABLE THAT CAN MEASURE OXYGEN CONCENTRATION AND FLOW RATE SAFELY, BETWEEN THE ...

The present work deals with the design, development, testing and implementation of a real-time monitoring system to determine the particle size distribution of soot. The novel technique shall make use of multiwavelength analysis of light scattering properties of the particles to infer the particle index of refraction, the soot number density and the particle size distribution. The Phase I technica ...

THE TREMENDOUS BANDWIDTH OF OPTICAL FIBERS HAS LED TO THEIR USE IN OPTICAL TELECOMMUNICATIONS AND LOCAL AREA NETWORKS (LAN). TIME DIVISION MULTIPLEXING (TDM) AND CODE DIVISION MULTIPLEXING (CDM) ARE BOTH RESTRICTED BY ELECTRONICS AND ELECTROOPTICS, WHICH LIMIT THE THROUGHPUT TO LESS THAN 20 GB/S. WAVELENGTH DIVISION MULTIPLEXING WDM) ALLOWS HIGH LEVEL OF CONCURRENCY BETWEEN USERS AND COULD POTENTI ...
