The NIST patented six-degree of freedom micropositioner technology associated with this subtopic has been identified by E M Optomechanical, Inc. (EMOM) as a technology that could be incorporated into the company¿s long-working distance interference microscopes. A key element in these microscopes is a piezo-actuator device, installed in a manual pitch/yaw mount, which translates a small flat mirro ...

Modern supercontinuum (SC) light sources are generated by non-linear interactions between ultrashort laser pulses and optical fibers. These light sources have high brightness and are spatially coherent. Output in near-ultraviolet to near-infrared wavelength ranges has been demonstrated. SC wavelength ranges are constrained by the transmission and dispersion properties of the fibers. Previously, ou ...

Southwest Sciences¿ Phase 2 SBIR project will lead to development of residential fire sensing systems based on recently developed, low cost temperature and optical imaging sensors combined with newly introduced highly miniaturized, micropower CO sensors. Sensor modules will be part of a low power wireless network. Each module will be about ½ the size of a business card, a few mm thick, and w ...

A key factor of international efforts to identify and suppress the supply of and demand for nuclear materials, and thereby to deter potential traffickers, is the ability to accurately identify contradicted material and ultimately to trace it back to its origin. Alpha particle spectroscopy is widely used in nuclear forensics to assay trace quantities of sensitive nuclear materials, but the limited ...

This Phase II SBIR Research project will continue the development and testing of an innovative instrument for measuring fluxes of atmospheric ammonia to be delivered at the end of Phase II. The instrument will combine advances in diode laser technology with sophisticated laser modulation methods to quantify ammonia in a low pressure flow cell. The instrument¿s small size and light weight will ...

Southwest Sciences proposes to develop an automated, fast, and compact instrument to measure tropospheric ammonia from light aircraft. Ammonia plays important roles in aerosol particle chemistry, and particle characteristics are critical in understanding climate change and air quality. Existing ammonia instruments are either too large or measure too slowly for use on light aircraft. The unique ...

We will develop two programs to process data describing a model geometry and convert it to input acceptable to the Monte Carlo transport codes MCNP and MCNPX. One program will read CAD files in the ACIS solid body SAT format. Solid bodies, surfaces, and cells described in the SAT file will be converted to equivalent MCNP objects where available. Where there is no MCNP equivalent, such as for splin ...

A long standing problem in oceanography and hydrography is accurate real-time measurement of offshore water levels. The Phase 1 research involved investigating a wide range of recent techniques and technologies, and performing analyses and trade-off studies to evaluate, select, and integrate them into a GPS-tracked buoy system (buoy, shore reference station for differential GPS, and repeater stati ...

This Phase I SBIR research project will investigate the feasibility of an ammonia sensor based on an antimonide laser and an advanced, low noise modulation spectroscopy method. The rapid response and high sensitivity will allow the use of the eddy correlation method to provide continuous measurement of ammonia flux. Minor adjustments to the laser operating point will allow the instrument to measur ...
