Low-cost Gas Imager

Methane is a potent greenhouse gas. Methane leaks can have significant safety risks with undetected leaks contributing to climate change.

GasSight, developed by researchers at the University of Glasgow, allows real-time video images of gas. Although gases are invisible to the naked eye, QuantIC have developed a camera, utitlising single-pixel imaging to create colour-coded images of the gas, providing a highly accurate real-time picture of the scene.

Real-time video imaging of gas has a key advantage over conventional technologies in that it can speed up the time required to locate a gas leak. Watching the gas flow in real-time conveys the direction from which it is dispersing. From this, the source of a leak can be determined. For gas utilities, and many other industrial settings, this technology offers reduced maintenance times for gas pipe infrastructure and improved safety.
