ABSTRACT: The overall objective of this project is to develop scalable simulation components that effectively model the meso-scale physics of heterogeneous energetic materials subject to dynamic shock loading including matrix debonding, void collapse, and damage due to crystal to crystal interactions, and bridges the meso-scale to the macro-scale for system scale simulations of the transition to d ...

ABSTRACT: An unseeded measurement technique is proposed for simultaneous spatially-resolved measurements of density, temperature, and velocity in hypersonic wind tunnel flows with the future potential for time-resolved measurement capability. A variant of filtered Rayleigh scattering (FRS) will be developed that takes advantage of unique monotonic relationships between molecular vapor cell filter ...

A diagnostic is proposed for obtaining instantaneous three-dimensional volumetric distributions of density in a flow field at velocities ranging from subsonic to supersonic. Two variants of laser-based Rayleigh scattering will be investigated, each of wh...

An experiment to obtain validation data on the transient aerothermoelastic response of a curved panel in hypersonic flows will be designed and evaluated for its feasibility. Significant challenges must be overcome for a successful experimental campaign i...

The modern warfighter faces the constant threat of endemic infections, multi-drug resistant bacteria and Biological Warfare Agents. In order to provide accurate front-line treatment that will curtail the overuse of antibiotics, a rapid and robust molecula

ABSTRACT: In this effort, Freedom Photonics will develop a high-sensitivity high-resolution coherent imaging system based on a Si avalanche photodiode (APD) array and corresponding bias and read-out electronics. This will be a monolithic APD and ROIC (readout-integrated-circuit) focal plane array (FPA) system. We start from a proven high-performance CMOS electronics backplane and build the photon ...

Advanced infrared imaging techniques are of great interest but associated high costs of III-V and II-VI SWIR and MWIR materials prohibit their widespread deployment and integration with other optoelectronic devices. Freedom Photonics and its team partner...

allowing the sensitive RF front-end to be located away from the now more compact phased array antenna. We are proposing a rugged photonic integrated spatial division multiplexing RF link for phased array system with low cost, size, weight and power cons...
