Description:The Phase I objective is to demonstrate the capabilities of Raman LIDAR for remote sensing of automobile emissions. A short range UV Raman LIDAR system will be developed to detect automobile emissions (NO, NO2, CO, CO2, hydrocarbons, etc.) by detecting the Raman backscatter with a pulsed UV laser source. The system will consist of a Cassegrain telescope, solid-state laser, and an extremely high sensitivity avalanche photodiode (APD) array detector. The system will capture the entire Raman return signal in a single pulse and convert the Raman return into pollution concentrations. The unique array of APD detectors will allow simultaneous acquisition of all the spectral components of the Raman return signal. The utilization of solid-state system components will result in a cost-effective, robust solution for remote sensing of automobile emissions.
The development of a remote sensing Raman LIDAR system for automobile emissions monitoring will significantly improve the ability to monitor on-road automobile pollution. EPA requirements for on-road monitoring of automobile emissions necessitates the deployment of remote sensing systems in states with excessive automobile pollution. By using short range UV Raman LIDAR, this on-road monitoring may be performed at arbitrary remote locations resulting in improved coverage of the automobile fleet.
