In industrial sectors spanning oil and gas, chemical processing, and environmental monitoring, gas leak detection represents a critical pillar of operational safety, asset protection, and regulatory compliance. Traditional leak detection methodologies—such as catalytic combustion sensors, electrochemical detectors, and manual sampling—often suffer from limitations including slow response times, limited detection ranges, and susceptibility to environmental interference. In recent years, advancements in optical sensing technologies have revolutionized leak detection paradigms, delivering unprecedented precision, remote operability, and real-time analytics. This article delves into the technical mechanisms, performance advantages, industrial applications, and future trajectories of optical leak detection systems—with a focus on infrared (IR) gas sensing and optical gas imaging (OGI) cameras—and their transformative impact on industrial safety and environmental stewardship.
