Aculight proposes to develop a laser source that will enable NIST to perform highly sensitive water vapor detection via cavity ring-down spectroscopy. The source will operate over a wavelength region centered at 1380nm. It will be based upon frequency conversion of a single frequency fiber source using an optical parametric oscillator (OPO).The performance of the source in terms of several critica ...

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 ...

THE PURPOSE FOR THE METHODOLOGY IS TO PROVIDE SYSTEMS MANAGERS (AND THEIR ADVISERS) A METHOD FOR ENSURING THE COST-EFFECTIVE SURVIVABILITY TECHNIQUES ARE INCLUDED IN THE SYSTEMS PLANNING IN EARLY STAGES. THE INTENT OF THE PROPOSAL IS TO SUPPORT IMPLEMENTATION ...

THE CONTRACTOR HAS PATENTED TECHNOLOGY FOR A UNIQUE PROCESS THAT DIRECTLY CONVERTS AN ACOUSTIC SIGNAL INTO A VISIBLE ONE IN REAL-TIME WITHOUT ELECTRONIC CIRCUITRY. THIS RELIES ON THE ACOUSTO-OPTICAL PROPERTIES OF A CONTINUOUS LAYER OF LIQUID CRYSTAL THIN FILM LAYER WHICH SERVES AS BOTH THE SENSOR AND THE DISPLAY. THE IMAGE CAN BE VIEWED DIRECTLY BY MEANS OF CCD CAMERA. HOLOGRAPHY PROVIDES FOR BOTH ...

The primary objective of the Phase 1 program was the development of optical fiber devices and cost-effective signal conditioning systems to produce commercially available composite process monitoring systems. The tasks successfully completed during the Phase 1 effort are as follows: (1) examined the performance requirements of the optical fiber devices and demodulation systems for FT-IR- and fluor ...

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 ...

The AWIPS (Advanced Weather Information Processing System) program is a cornerstone element supporting NWS' mission to protect life and property and enhance the national economy. The challenge of this project is to help NWS harness large amounts of unused computer resources and underutilized data, improve collaboration and cooperation to solve complex problems not currently addressable, to increas ...

Large X-ray generators using gas fill loads are a key element in the DTRA simulator program. Consistent relative timing between the injection of the gas shell and the generator current pulse is crucial to producing consistent, high-yield x-ray pulses.To that end HY-Tech proposes replacing existing high voltage trigger pin technology, with a sensitive, all fiber-optic heterodyne interferometer ba ...
