Gas sensing surveillance system

Abstract

A gas sensing surveillance system integrates a tuneable diode laser absorption spectroscopy (TDLAS) sensor system with a camera to detect and visualize gas leaks, smoke and particulates. The system is housed in a specially designed housing that protects the TDLAS sensor system from environmental factors and physical damage. The housing also contains power and control systems that coordinate the functioning of both components. An optical window with mechanical actuators and optical-filters is used to reduce optical interference and improve performance. The configuration of the housing to accommodate both the Camera and TDLAS sensor system allows visualization of the presence of gas leaks or particulate and smoke or distances to an area of interest in space. The system can accurately measure gas concentration and improve the sensitivity and specificity of gas leak detection.
