Tensile-strained germanium tin structures will be developed for infrared emitters and detectors that are compatible with silicon fabrication processes.Optical detectors in the wavelength range of 2-5 microns will be developed by using GeSn on silicon ...

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...

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: The sensor system requirements for image based navigation that uses passive millimeter wave imaging radiometry will be established based on existing RelNav and AbsNav algorithms that were demonstrated to work in multi-modal imagery. Existing flight data will be used to simulate the PMMW imagery for these tests. A preliminary design of such a PMMW system will be created. Under Phase-II th ...

ABSTRACT: The proliferation of autonomous- and human-machine systems necessitates the creation of new tools for system design and evaluation. Key among these are simulation testbeds that support interactions between multiple warfighters and systems, and methods for creating and integrating intelligent agent models into simulation environments. We see a significant opportunity to advance the state ...

ABSTRACT: XL Scientific LLC will leverage over a half a century of High Power Microwave (HPM) Effects Test and Modeling experience to develop an integrated DREAM2 toolkit that models the vulnerability and susceptibility of electronic systems, subsystems and components to directed energy (DE) HPM weapons. The analysis toolkit developed will center on three essential modules, critical in a full asse ...

ABSTRACT: The objective of this proposal is to develop a fast axis collimating lens for quantum cascade lasers (QCL) which emit in the midwave-infrared (MWIR) range. These lenses must withstand the stress of both continuous wave (CW) and pulsed laser emission. These high laser powers may cause ablation of lens material reducing effectiveness of the optic and leading to failure. Thus, a high damage ...

ABSTRACT: Digital binocular helmet-mounted display (HMD) systems are now available that allow high resolution wide field-of-view (WFOV) digital imagery to be displayed on high resolution microdisplays. These digital HMD systems require a low-latency embedded vision processor (LLEVS) capable of implementing the necessary image processing algorithms. An SA Photonics LLEVS will be implemented on next ...

ABSTRACT: Designing an efficient and effective film cooling system to protect critical components of modern rocket engines requires a significant number of challenges to be addressed. Complicating the already difficult hydrodynamic challenges, thermal cracking of hydrocarbon fuels is always accompanied by coke formation. The coke deposits on the combustor and nozzle walls reduces heat fluxes and c ...

ABSTRACT: The objective of this proposal is to demonstrate the feasibility of a flexible, low-cost, integrated and sensitive broad spectrum optical property characterization system. We propose a hyperspectral imager designed for operation in the 300nm 2000nm spectral region with state-of-the-art spectral and spatial resolution through the use of a high density array of high finesse (F = 1000) tuna ...
