To address the U.S. Air Force need for Developing innovative wave-optics Propagation methods to model laser systems that are faster, efficient and more accurate, Luminit, LLC, and University of Southern California (USC) propose to develop Wave-Optic Propagation Computation Enabled by Machine Learning Algorithms (WOPA). The proposed algorithms will be based on cutting off redundant frequencies upon ...

This Small Business Technology Transfer Phase I project will develop ultradense, low-power plasmonic integration components and devices for on-chip manipulation and processing of optical signals. Both passive and active components will be studied. Detailed performance predictions will be obtained through finite element modeling (FEM) of the harmonic Maxwell’s equations. The FEM provides detai ...

Recent advances and successes of deep learning neural networks (DLNN) techniques and architectures have been well publicized over the last several years. Voluminous, high-quality and annotated training data, or trial and error in a realistic environment, is required to achieve the promised performance potential of DLNNs. Unfortunately for DoD and/or Intelligence Community (IC) applications of mult ...

The imaging vibrometer development will be based on a representative Directed Energy (DE) aperture assumed to be 30 cm. This effort will provide both DE and Combat IDentification (CID), modes for relative short range DE operations, and an ISR Combat IDentification (CID) mode for operation at extended range. A combination of analytic derivations and wave optics simulations will be used to define a ...

Locating objects that vibrate is a way to discern potential threats and locate targets. However, current vibrometry technology typically measures only the global vibration of target and cannot create an extended spatial measurement of the vibration profile of the target. These solutions cannot identify what the target is, nor can they locate potential weak spots on the target, because they lack sp ...

High-speed and reliable tactical communications have empowered the Air Force with overwhelming information superiority, and control of the battlespace. However, the effectiveness of such systems has been impacted by the increasingly congested and contested spectral environment, compounded by the reliance on half-duplex systems. The latter rely on time- or frequency-division to separate transmit an ...

Higher efficiency solar cells are needed to reduce solar array mass, volume, and cost for Air Force space missions. Intermediate-band quantum-dot (QD) solar cells can yield dramatically higher efficiencies than current multi-junction (MJ) technologies. However, several issues must be addressed to demonstrate manufacturable, high efficiency devices. CFDRC aims to develop: 1) High-efficiency, ligh ...

Spectral Energies proposes to design a multisensory diagnostic suite for measurements within elevated-pressure RDEs. This sensor will utilize tunable-laser absorption spectroscopy to measure temperature, pressure and H2O concentrations in the annulus of a rocket-RDE and background-oriented schlieren imaging system for flow density gradient imaging to provide time resolved information about the sho ...

We propose to develop ultradense plasmonic integrated devices and circuits for optical interconnect compatible with the electronic circuitry. In our proposal, we will employ engineered metallic nanostructures that combine energy concentration by plasmonic lenses and retardation-based plasmonic resonances to even further boost the efficiency of materials exhibiting optical nonlinearity. These plas ...

UbiHere, a Columbus Ohio based small business, has developed, in conjunction with The Ohio State University, a unique highly capable low-cost system to address the known issues with GPS denied tracking of assets, equipment or people in indoor and outdoor operating environments. UbiHere’s commercial system is comprised of an application specific electronics tag, designed by the company, whic ...
