This Phase I project has two primary objectives. The first objective is to evaluate the feasibility of a fully ion implanted fabrication process based on the heterodimensional 2-D MESFET. The new device, the 2-D JFET, will have p+ ion implanted sidegates which laterally modulate a thin, highly doped n-type conducting channel. The 2-D JFET should have excellent high speed, low power characteristics ...

Brimrose proposes to produce an improved material for optical power l miting at near infrared wavelengths to protect sensors against jamming and to build a prototype device. The proposed material, vanadium doped cadmium telluride, is relatively new and will be used to fabricate an electro-optic power limiter (EOPL). This approach of using a doped II-VI semiconductor for power limiting was first de ...

Using newly developed II-VI photorefractive semiconductors as time integrator and high performance TeO2 acousto optic deflectors (AODs), Brimrose proposes to develop a compact RF signal processor useful in radar signal processing. The high sensitivity of this relatively new photorefractives, in the wavelength range of 0.63ym to 1.6,um, will allow signal processing using low power near infrared las ...

The proposed effort will apply advanced methods of hybrid learning to problems of detection and identification of sensory events (e.g., boost phase evens). Our approach aims at building a vision system capable of hybrid learning, in which symbolic (rule-based) and subsymbolic (neural network) strategies are integrated to achieve high efficiency and accuracy both in learning human comprehensible se ...

Epitaxial Technologies proposes to develop the enabling material technology for the fabrication of programmable multi-wavelength photodetector arrays. We will perform material and device design to determlne suitable material structures and epitaxial wafer growth processes. We will investigate the use of compound semiconductor structures lattice matched to InP. The main goal of this proposed Phase ...

Novel ionic self-assembled monolayer (ISAM) processes for the fabrication of advanced electronic materials and devices will be developed through this program. Revolutionary ISAM methods to create nanostructured multi-layer inorganic/organic thin-films offer major advantages over conventional manufacturing processes, since the process is simple, low-cost and environmentally friendly in that no vola ...

F&S and Virginia Tech will cooperatively develop high performance protective ionic self-assembled monolayer (ISAM) organic/inorganic coatings for space-based optical and structural components, and work with Litton to upscale practical coating manufacturing. Revolutionary ISAM methods of creating multi-layer protective nanopartwcle films offer major advantages over con-ventional coating processes, ...

Large-screen (over 35" diagonal length) wall-hanging displays have many applications in BMDO, such as flight simulation, command control center display, mission rehearsal and training, virtual reality environment development. They are also highly demanded in consumer electronics industries, such as high definition TV (HDTV), and electronic instrumentation. However, the current costs of most large ...

This proposal presents a novel design concept to build linear and rotary uinchwormX type of actuators that can be used as active elements for static precision positioning and active strcutural dynamic control in BMDO's space structures and flight vehicles. The proposed actuator, call the Solid State Stepper Motor, exploits solid state Lead Zirconium Titanate (PZT) materials as the synchronized dri ...

To the best of our knowledge, there is no existing battle field modeling or reconnaissance technology that can provide both the real-time three dimensional (3D) range information and the omni-directional viewing capability at any cost. The primary objective of this project is to fill this gap, and to develop a high speed and low-cost 3D image sensor with an omni viewing angle (i.e., 360 degree) fo ...
