Optical correlators are known to be fastest engine for template based image recognition. There are, however, applications that require speeds even faster than the best optical correlators have accomplished. This effort will demonstrate the Hybrid Electrical-Optical Resonator for Image Classification (HEORIC) and correlation plane discrimination enhancement. The HEORIC has been demonstrated in simu ...

Optomec Design Company proposes to use Laser Engineered Net Shaping (LENSTM), a Rapid Prototyping and Manufacturing (RP&M) technology currently under development at Sandia National Laboratories (SNL), as a new method for integrating instrumentation (e.g., embedded sensors) into metal structural components. SNL has demonstrated the ability of the LENSTM technology to produce near net shape stainles ...

Voltage surge-induced electronic failures represent a multibillion dollar problem for the U. S. and world microelectronics industry. Typical sources of voltage surge are electrostatic discharge from the human body, line transients from parallel AC power fluctuations, and lightning strikes. In military and missile electronics there exists the particular threat due to electromagnetic pulse (EMP) wh ...

Pacific-Sierra Research Corporation (PSR) proposes to design a portable instrument to determine the long wave infrared (LWIR) characteristics of any EO sensor. Such an instrument would be valuable in LWIR sensor flightline testing, production checks, and foreign material exploitation. This field/production instrument would automatically provide detailed performance information for CM vulnerability ...

Pacific-Sierra Research Corporation (PSR) proposes to develop a robotic alignment system for aircraft assembly using its non-contact thermographic technology. This automated robotic-thermographic positioning system will be capable of accurately locating and monitoring subsurface holes and edges under exterior panels or skins. The non-contact thermographic system will include a portable high-spee ...

The recent development of the CMOS active pixel sensor (APS) by the proposers during their former employment at NASA's Jet Propulsion Laboratory has, for the first time, permitted large scale integration of supporting circuitry and smart camera functions on the same chip as a high performance image sensor. One of the major challenges facing any image sensor is the ability to handle scenes with wi ...

Physical Optics Corporation (POC) proposes to design schemes that will extend multiuser detection and interference suppression technologies. This will be done in the context of multiuser Code Division Multiple Access (CDMA) communications for wireless multirate and variable-rate network communication applications. The importance of this project lies in its combination of advanced technologies wit ...

Physical Optics Corporation (POC) proposes to develop an innovative high Resolution Acousto-optic Imaging Sensor (RAIS) device based on limitations of existing technologies for underwater imaging. The compactly packaged RAIS device comprises an AOLCD, ultrasound generator, acoustic lens, and CCD camera. The acoustic ultrasound transducers produce ultrasonic waves. The acoustic waves propagating ...

A new light source using dielectric solids has been under development since the 1980s for thermophotovoltaic (TPV) generation of electricity. The light source is a dielectric refractory solid emitter heated to relatively high temperatures (~1 500_C) by combustion, nuclear or other heat sources. This new light technology has now reached the maturity to be applied to the optical pumping of high powe ...

An entirely new light source using dielectric solids has been developed by Quantum Group Inc. to power thermophotovoltaics and to pump lasers. The light source is a refractory solid emitter heated to relatively high temperatures (~1500_C) by combustion, nuclear or other heat sources. For the new light source, a dielectric solid is chosen to have selective thermal emission ("superemissive") with ne ...
