ABSTRACT: This project aims to develop a Short Wave Infrared band image projector to provide real time detector stimulation with high dynamic range. Our emitter technology is based on GaInAsSb quaternary semiconductor LED arrays hybridized to CMOS read-in integrated circuits. This project leverages read-in circuit design and control electronics that were developed under SLEDS - a longer wavelengt ...

ABSTRACT: We propose to develop a lightweight, compact Cetane sensor interfaced to a fiberoptic probe immersed in the RPA fuel tank to continuously measure, update and report Cetane number to the engine electronics for control of engine settings for RPA internal combustion engines (ICE) operating on heavy fuels. The sensor will be based on laser light scattering and will be made small and light ...

ABSTRACT: Flow Modeling and Simulation, LLC (FMS), proposes to develop a computational software tool, herein designated AUG3D, that is intended to provide physics-based, multi-level, validated computational simulations of turbine engine component flow fields, particularly those associated with thrust augmentors, i.e., afterburners. This tool will be ideally suited for closely integrating physica ...

In the proposed effort, we will leverage this extensive experience and capabilities to realize a frequency agile mmW radiometer that can cover the range of DC-110 GHz and can be scaled to DC-200 GHz under Phase II. Ours is a photonic system that multiplies and up-coverts a low-frequency reference signal onto an optical carrier (laser) using EO modulation, then uses the modulation sidebands to inj ...

ABSTRACT: In this SBIR effort we will develop a packaging process and demonstrate (Phase I) a prototype of high power Photodiode (PD) that has a normal incident, pigtailed fiber input and a coaxial RF output that operates from DC to>60GHz. We will apply and extend (Phase II) the aforementioned packaging process to single PD, balanced PD and array of PDs that work from DC through entire W-band. De ...

In this proposal, Alphasense, Inc. details the development of a novel microwave NDE sensor for defect inspections in silicon nitride bearing balls. The key innovations of this proposal include the following: a) the use of the spherical bearing ball as a dielectric resonator, thus enabling us to correlate the resonance characteristics of the bearing ball with various defects; b) the measurements in ...

Bridger Photonics proposes to prove the feasibility of an innovative method for multi-mode target identification. To achieve this system, the team will combine the most advanced ultra-high-resolution FM-CW LADAR unit in existence with state-of-the-art feature-specific computational imaging concepts. This marriage will enable the team to identify and realize the truly optimal solution to the Air ...

The European Union''s RoHS and WEE Directives mandated the elimination of the carcinogenic, hexavalent chromium coatings for metals, including magnesium and zinc-nickel plated substrates.  The purpose of this project is to find chemistry that will meet requirements of industry performance specifications and of the mandate.  METALAST intends to explore trivalent chromium in conjunction with two o ...

Current mixing and casting procedures result in unwanted gradients in solid rocket motor (SRM) material properties with subsequent ballistic property variations.  Resodyn Corporations¡¦ ResonantAcoustic¥ mixing (RAM) technology is poised to revolutionize the design, development and production of SRM¡¦s.  RAM technology has the unique capability of rapidly mixing high solids propellant witho ...

The major requirements for this program include the modeling of optical switching fabric technologies appropriate to space-borne systems at very high speed. Specifically, this program will evaluate two OptiComp candidate optical transceiver technologies against a Serial Rapid IO switching fabric. A down-selection to one optical transceiver technology will be made. Then, a simulation of that Serial ...
