Methane Gas Imaging

Caption

Researchers developed a new infrared imaging system that could one day offer low-cost, real-time detection of methane gas leaks. The top row shows movie frames from a low-resolution (16x16) computational image of a gas leak, overlaid onto a high-resolution color image from a CMOS camera. Only the methane gas is detected (red), when 0.2 liters per minute of methane are delivered via the green tube and 2 liters per minute of nitrogen are delivered from the red tube. The bottom row shows movie frames where a methane gas sample cell is moved by hand across the field-of-view.
