In Phase I we demonstrated a novel in-situ cleaning technique based on UV-activated surface reactions involving ozone and hydrogen to remove organic adsorbates and chemically-bonded impurities, e.g oxides, from the substrate surface. In Phase II the program will develop this process to significantly decrease the density of material defects in large-format, infrared, focal-plane arrays. Electrica ...

A collaboration between Amethyst Research Inc., University Multispectral Laboratories (a government-owned, contractor-operated nonprofit corporation), and Teledyne Imaging Systems (a large defense contractor) proposes to develop/improve high-performance infrared sensors based on Type II, strained-layer superlattices (SLS). Such sensors offer (theoretical) advantages over state-of-the-art HgCdTe p ...

We propose to demonstrate the feasibility of using time domain terahertz measurements to locate, identify and image defects and material variations within advanced composite materials used in missile radomes. We will investigate the time and frequency domain transmission properties of radome materials to determine their intrinsic terahertz electrical properties and prove the detectability of defec ...

Improved performance SWIR sensors with extended wavelength response to 2.5 microns will be developed using two disruptive technologies with which Amethyst has demonstrated success: nBn detector structures and defect passivation via hydrogenation. Similar to conventional extended wavelength photodiodes, the improved sensors will based on mismatched InGaAs grown on graded buffer layers on InP substr ...

This Small Business Innovation research Phase I proposes the development of a practical and reliable in-vitro test for detecting the evidence of Mycobacterium tuberculosis (MTB) infection as an alternative to the tuberculin skin test (PPD-TST) and to the interferon gamma release assays (IGRAs). The proposed methodology will be a powerful detection technology in clinical diagnosis owing to its dete ...

ABSTRACT: The engineer will be guided through the creation of criteria, alternatives and evaluation techniques in order to make a better decision. BENEFIT: The engineer will be guided through the creation of criteria, alternatives and evaluation techniques in order to make a better decision.

ABSTRACT: This proposal proposes to develop an agile methodology to identify bad actor parts to proactively address part performance. The methodology with algorithms and models will be developed by merging ideas from different areas of Science and Engineering. Some of the algorithms and models to researched for methodology development are ranking models, record-linkage algorithms, Hidden markov ...

ABSTRACT: As we move from a paper-based world into a digital environment, the internet will soon evolve from a virtual documentation system into a vibrant ecosystem of data where documents and human actors play an even smaller role. We are currently reaching a tipping point in history concerning data: more data is being manufactured by machines, servers, mobile devices, and software applications ...
