A new concept for the detection and tracking of toxic or flammable gases resulting from accidental spills or leaks is presented. The BAGI technique (backscatter/absorption gas imaging) integrates a laser and a “flying-spot” imager, and allows the normally invisible gases to be visualized on a standard TV monitor. BAGI parameters for a natural gas-detection system are discussed.
