摘　　要：汽车尾气排放已成为最主要的城市污染源之一。汽车尾气的遥感监测系统作为一种高效实时监测汽车正常运行状况下的尾气排放方法已越来越受到人们的广泛关注。本文主要介绍基于可调二极管激光(TDL)技术的汽车尾气遥感监测系统。首先介绍遥感监测系统的产生与发展以及TDL技术的基本原理,其次阐述遥感监测系统的组成、关键技术以及系统的优点,并分析遥感监测系统在国内外的应用现状,最后提出目前应用中尚待解决的若干关键技术问题。Vehicle emission is one of the major sources of urban air pollution. As an effective real-time method of monitoring vehicle emission under normal driving operation, great attention has been paid to the remote sensing technology of vehicle emission in recent years. A remote sensing system of vehicle emission based on the tunable diode laser technology is presented in this paper. The research and development status of remote sensing system and basic principle of tunable diode laser technology are first introduced. The composition and key technology, as well as the advantages of this system are then presented, the application status of remote sensing system at home and abroad are also surveyed. Some key technical problems in current real applications are finally proposed.
