ABSTRACT: The demonstration of 155 Kelvin refrigeration by optical cooling performed by the co-PIs of this proposal is a first step toward revolutionizing Air Force cryogenic systems. The stated focus of this STTR solicitation is"developing the concepts of a solid-state optical cryocooler that can approach 100 K with a cooling power exceeding 200 mW."To achieve this performance, a crucial propose ...

ABSTRACT: Developing the quick strike capability of the Air Force requires hypersonic testing using advanced instrumentation to determine key aerodynamic parameters. A novel method for stand-off measurement of gas velocity is proposed. The method should operate over a wide dynamic range, from still air to hypersonic velocities. The method is non-contacting, precise, and spatially-resolved. It doe ...

ABSTRACT: The behavior of the Chalcogenide based ion-conducting memristor lends itself for use as an element in a simple neuromorphic computing circuit. The reaction of a circuit to an external stimulus may be the result of its ability to learn from previous similar, yet unrelated exposures to environmental stimulus. A highly specialized variation of the memristor, previously developed by the Ad ...

ABSTRACT: We propose a revolutionary method for constructing autonomous self-organizing circuits via memristive and CMOS technologies for use in autonomous flying vehicles. Our method utilizes a simple but powerful plasticity rule that can be mapped to the physics of memristive devices acting as synaptic elements whiten neuromorphic circuits. Through self-configuration of router and logic struc ...

ABSTRACT: Recent Airborne Tactical Laser (ATL) field testing demonstrated that high-energy laser (HEL)-induced obscurants could break the tracking systems lock on the aimpoint, negating the HEL attack. When an HEL engages a target surface, particles may be emitted from the surface that obscure the target, change the optical signature, and attenuate the beam on target due to scatter and absorptio ...

ABSTRACT: The Wideband Optical C3 System (WiBOC3S) is proposed using the current Free Space Optical (FSO) communications subsystem, specifically designed for short range surface-to-surface (including airborne) covert data links. The proposed miniaturized subsystem will have high data bandwidth (2.5 Gbps), with fast pointing and tracking capability. Adding the fieldable hand held C2 interface (Uni ...

A research effort is described that will develop high fidelity design tools and, in Phase II, the implementation of a reliable phase-locked magnetron pair based on the California Tube Laboratory (CTL) CWM-75/100L magnetron. Two approaches to phase locking will be examined and modeled in this Phase I effort; i) phase locking via an anode-side cavity field probe, and ii) phase locking via a grid-cat ...

Narrowband high-power microwave sources are under development for possible military applications. Defeating improvised explosive devices (anti-IED) and non-lethal anti-personnel effects are both of interest. The possible success of meeting the requirements of these applications can be increased by combining, in a coherent manner, the output of several microwave tubes. Magnetrons, being the most ...

The Air Force is exploring and developing several aircraft mounted high energy laser (HEL) systems for precision strike and self- defense missions such as the Air Force"s new HEL demonstration program, Electric Laser on a Large Aircraft (ELLA). All HEL systems require accurate pointing and precise stabilization of the laser beam to be effective. Laser systems hosted on aircraft platforms pose an a ...

ABSTRACT: Primordial, Panoptic, and intuVision propose the development of Tentaclea multi-camera immersive surveillance system that synthesizes information from hundreds of video streams into an intuitive 3D representation. Team Primordial will start with our existing state-of-the-art baseline componentsPanoptic C-Thru, intuVision Panoptes, and intuVision Video Recallwhich already fully meet 6 a ...
