There has been continuous improvement in commercial Land Cellular telephone technology since deployment of the first analog system - Advanced Mobile Phone Service - in 1984. Each new generation of air interface embodies increasingly sophisticated signal modulation schemes providing improved spectrum utilization and network capacity. Today, a state-of-the-art commercial digital Cellular ...

We propose developing a diode laser-based full-spectrum Raman scattering instrument prototype incorporating fiberoptic coupling for rapid, continuous on-line and remote monitoring of fuels. Raman's narrow, well-defined peaks and its insensitivity to moisture contamination allow for full-spectrum detection with 0.1% sensitivity for liquids and with 30 to 60 second response times. Traditional Raman ...

This proposal describes the feasibility and design study of a system for detection and imaging light and dense non aqueous phase liquids (so called LNAPLs and DNAPOLs) that have contaminated soils and aquifers. The system will make use of several modalities to improve combined spatial resolution and selectivity for detecting and imaging aquifers, LNAPLs and DNAPOLs. To accomplish a broader spect ...

The need for powerful personal monitoring equipment to alert military personnel to impending chemical threats is clear. The development of sophisticated monitoring equipment which may be carried on a belt or in a pocket has largely been restricted to chemical sensors which tend to lack sufficcient specificity to offer adequate protection while minimizing false alarms. The present proposal is to in ...

We propose to determine the feasibility of using diode-laser-based, full-spectrum Raman scattering technology incorporating fiber-optic coupling for rapid, continuous, on-line detection and monitoring of key intravenous (IV) drugs. Raman's narrow, well-defined peaks and insensitivity to water offers potential for full-spectrum Raman detection of drug levels in blood with parts per millions (ppm) ...
