methyst Research Inc. will design, fabricate and test a high uniformity, large area, low noise infrared trap-detector detector for the 1- 4.5 μm wavelength range. This state of the art detector will have a large area (e.g., 1-1.8 cm diameter active area) with a spatial variability of internal quantum efficiency of less than 0.1 % between 1 μm and 4.5 μm. In addition, the internal quantum effici ...

Magnetic resonance imaging (MRI) has become a primary diagnostic tool in scientific research and clinical imaging. Despite the excellent image quality that can be obtained with today’s MRIs, images acquired using different MRI systems and during longitudinal studies are not reproducible, and hence can be difficult, if not impossible, to compare. To address this issue, a standardized test of the ...

Thin film multilayers of nanometer scale thickness are fundamental to the future of electronics and communications technologies. Chemical depth profiling by ion etching techniques are critical to the characterization of these structures. A fundamental problem with current ion etching technologies is that typical ion energies (~1k eV to 20 keV) create extensive damage and intermixing of nanometer t ...

Next-generation smart machine tools are currently under research and development. Critical to the success of these tools will be the inclusion of smart sensors. These sensor suites will need to measure physical parameters such as temperature, vibration, pressure and so on. Luna Innovations has extensive experience in developing solar powered wireless systems to transmit sensor data. Luna proposes ...

This Small Business Innovation Research Phase 1 project proposes to develop a femtosecond laser system optimized for optical clocks and other precision metrology applications. In principle, atomic optical transitions have the potential to provide radically higher-accuracy timekeeping, because of the very high frequency of an optical transition. The problem of counting, or down-counting, the oscill ...

We propose to compare alternative architectures for phase noise measurement by directly sampling the RF waveform. Out of band modulation and cross correlation will reduce noise. The capabilities of each architecture will be determined using analysis and simulation. The results will be used to determine the feasibility of developing a commercially useful measurement instrument. If the results are p ...

The near chiral purity of the biosphere leads to a vast array of chiro-specific physiological responses. This chiro-specificity, in turn, gives rise to the need for the manufacturing of enantiomerically pure chiral chemicals, such as pesticides, pharmaceuticals, food additives, pigments, etc. Critical to the efficacy of both chiro-specific biology and chiro-synthesis/separation are the interfacial ...

We will develop a compact external cavity stabilization system, which will employ independent electro-optic control over the optical path length of the cavity and a wavelength-selective element. The system should be able to cover a 30 nm range and give mode-hop-free tuning over 20 nm intervals. The design of the feedback system will be compatible with any commercially available laser diode from 63 ...
