The article presents the findings of main recent research and development works conducted for gas leak detection and measurement. Higher emphasis are considered for 2-D arrays sensors because of the wider coverage area they can handle in real-time, especially if they are carried within moving vehicles such as drones, helicopters, and satellites. This includes long-wave infrared (LWIR)- and medium-wave infrared (MWIR)-imaging systems. In spite of their success to accurately detect, localize, and even quantify leaks, under certain conditions, LWIR and MWIR imaging systems still face several challenges. This prevented them to continuously operate in all environmental conditions and within a reasonable long period of time. Thus, the article also presents other alternative technologies which can potentially complement or substitute LWIR and MWIR techniques. This includes photoacoustic, temperature profiling, and short-wave infrared (SWIR)-based techniques. The article can be a useful resource to help deciding which of these techniques can be used for a particular gas leak-detection application.

气体泄漏检测和测量系统：前景和未来趋势


本文介绍了气体泄漏检测和测量的最新主要研究和开发工作的结果。二维阵列传感器受到更高的重视，因为它们可以实时处理更广泛的覆盖区域，特别是如果它们被携带在移动车辆（例如无人机、直升机和卫星）内。这包括长波红外 (LWIR) 和中波红外 (MWIR) 成像系统。尽管长波红外和中波红外成像系统成功地准确检测、定位甚至量化泄漏，但在某些条件下，它们仍然面临一些挑战。这使得它们无法在所有环境条件下并在合理的较长时间内持续运行。因此，本文还介绍了其他可能补充或替代长波红外和中波红外技术的替代技术。这包括光声、温度分析和基于短波红外 (SWIR) 的技术。本文是一个有用的资源，可帮助确定哪些技术可用于特定的气体泄漏检测应用。
