Advanced Photonics Technology (APT) proposes to develop novel, wide-band, highly linear integrated-optical modulators based on low-loss waveguides in ferroelectric (e.g., lithium niobate and lithium tantalate) crystals with domain-inverted sections. The application of domain inversion to electro-optical modulators introduces a novel approach that allows the development of devices with low levels o ...

AstroPower proposes to develop high performance, room temperature, mass-producible, low-cost infrared detectors using liquid-phase heteroepitaxy of lattice-matched InGaAsSb and AlGaAsSb on GaSb substrates. The structure of these detectors will be a Separate Absorption and Multiplication Avalanche Photodiode (SAM-APD). This structure has proven to be an effective means of producing large gain in ...

"The U.S. Army is conducting extensive research involving the development of innovative algorithms for detecting and classifying high-value military targets using LADAR sensors. Many of these designs employ a model-based approach in which targets,background, and target/background interactions are modeled. A central tenet of this approach is that the large number of target, sensor, and background ...

The free-space characterization of an anechoic chamber is presently accomplished by conducting difficult and tedious RF measurements of the interference field intensity levels. Anechoic chambers are characterized after initial construction to determine the quiet zones where the creation of free-space conditions is being attempted. When systems under test (SUT) are placed in the chamber, degradatio ...

It is evident that having a standard multispectral environment capable of supporting a wide variety of users is crucial to promoting widespread use of any standard M&S architecture and reusability among the players and player components developed for such an architecture. A standard environment will provide for greater player portability and reusability since players would not be linked to a uniq ...

Proposed research involves the development of a system specification for a calibrated, infrared, focal plane array imager. A thorough review of LWIR and MWIR sensor manufacturing capability within the US wil be conducted. In addition, candidate companies will be selected to pursue more in-depth performance issues during on-site visits. Analysis of individual IR systems will be included along wi ...

Smart IR weapons must have excellent IR sensor characteristics that exploit as much information as possible to ensure guidance accuracy with low false alarms. Quantum Well Infrared Photoconductors (QWIPs) offer an opportunity to explore long wavelength polarization characteristics. A great deal of attention has been directed toward creating 2D gratings that produce large coupling coefficient. O ...

"Future space-based radar systems (SBRS) are expected to be critical to defense intelligence and modern battlefield analysis. SBRS design concepts involve thermal control issues exacerbated by low thermal mass, high radiative losses, and pressure to meetdesign areal densities of 4 to 6 kg/m2. To address these issues Eclipse Energy Systems, Inc. has developed prototype designs for electrochromic de ...

"Colored Petri Nets (CPNs) are now accepted as a powerful and general graphical language for designing complex systems. Several CPN editors, including Modasco's VSO Design, are now available or in development. However, these tools do not restrict the modelarchitect to realistic designs that satisfy the system's physical and functional requirements. Recent investigations by Modasco indicate that VS ...
