Paper Abstract

This paper presents a summary of Optech's internal studies into the feasibility of developing lidar systems for gas detection and mapping for environmental monitoring. The paper summarizes our evaluations of the capabilities of two different lidar techniques to address this area of application. These two techniques are Raman scattering and differential absorption. Optech has experience in building lidar systems operating on either of these techniques, and in recent years has carried out several studies of the potential of these lidar technologies for pollution monitoring. The paper includes brief reviews of the basic measurement techniques for DIAL and Raman lidar and examples of currently operating systems are given. Some of the practical problems encountered in operating these systems are also discussed. The results of performance models for new system concepts are then presented for a number of important pollution gases. The discussion then addresses the limitations of the current technology, by considering issues such as limitations of the existing laser technology and factors affecting detection limits.
