Standard Digital CMOS silicon circuits will have high quality Thin Film emitters, and modulators integrated on to the silicon using epitaxial liftoff and results in low cost opto-electronics in the near future. ABJ Integration is a leader in the field and proposes to design an optimized FPA readout system using this technology. Both emitters and modulators as signal sources will be investigated.

Active Control eXperts, Inc. (ACX) proposes to apply its expertise in actuator and control system design to high force, high bandwidth machine tool position control applications. ACX proposes to develop novel hybrid linear actuators which can operate at high loads (greater than 1000 lbs.) at high bandwidths (in excess of 200 Hz), and at high displacements (0.018 inches). This innovative solid-stat ...

Uses of the central visual field, or foveal scotoma, due to accidental exposure to laser light or macular disease can cause serious impairments in visually aided performance. Foveal scotomas also interfere with normal control of eye reations and saccades. Feasibility is tested for using electronic image shifting from scotomatous foveal retina to intact peripheral retina, as a con\mpensation for ce ...

The extension of classical frequency domain and wavelet transformation adaptive subband decompositions result in arbitrary time frequency til. The use of a time-varying tree-structured filterbank is proposed to provide a signal dependent transform which is capable of tracking non-stationarities via local reconfigurations. Under stationary assemptions, the filterbank converges to a unitary operat ...

INNOVATIVE TECHNIQUES ARE PROPOSED FOR INVESTIGATION IN A PHASE I EFFORT TO DETERMINE PASSIVE RF SURVEILLANCE AND TARGETING SENSORS AND ASSOCIATED METHODOLOGY FOR PERFORMING RAPID AND ACCURATE MEASUREMENTS OF RANGE/LOCATION OF OTH THREAT RF EMITTERS. THE ESSENTIAL PHYSICAL CONSTRAINTS TO BE OBSERVED ARE SENSOR COMPATIBILITYWITH, AND PORTABILITY OF THE ASSOCIATED RANGE DETERMINATION/ PROCESSING EQU ...

OHMIC CONTACTS ARE KEY TO THE IMPLEMENTATION OF SILICON CARBIDE (SIC) HIGH POWER, HIGH TEMPERATURE DEVICES. TO DATE, CONTACTS TO SiC MADE USING CONVENTIONAL TECHNIQUES HAVE DEMONSTRATED NEITHER LOW CONTACT RESISTANCES NOR LONG TERM STABILITY. IN PHASE I WE WILL DEVELOP LOW RESISTANCE SILICIDE BASED OHMIC CONTACTS SPECIFICALLY AIMED AT SiC HIGH TEMPERATURE, HIGH POWER DEVICES. CONTACTS WILL BE FABR ...

Infrared sensors and sensor arrays are widely used in military and commercial applications such as night vision, medical diagnosis and weather mapping. Expensive quantum effect sensors, such as HgCdTe systems, must be cooled to liquid nitrogen temperatures and are difficult to produce with uniform properties. A significant opportunity exists to dramatically improve detector fabrication and perform ...

Structural composites have many applications to 2500 Degrees F and beyond, in oxidizing environments. Oxide fibers within intermetallic or oxide matrices are the top candidate systems for satisfying these conditions. Suitable fiber/matrix interface coatings are critical, but their development has suffered from extremely high per-pound costs and marginal thermochemical stability. CaF2 and LaPO4 hav ...

The ability to control large amounts of power (1-150kW) is necessary in applications ranging from aerospace to consumer electronics to industrial power systems and transportation. In order for silicon and gallium arsenide devices to meet such high power densities, tens of devices must be combined to meet the voltage and current requirements. Power combining networks, extra heatsinking and sophisti ...

The superior optical properties of BBO and its applicability in frequency doublers and waveguides justifies development of thin film deposition processes which can be integrated with microelectronic processing. The high damage threshold of BBO, a necessary component for device integrity, is a major advantage over other nonlinear optic materials. In Phase I, chemical precursors and a deposition pro ...
