Abstract
This article describes use of photoacoustics by automakers to track and tackle leakage problems. Photoacoustics uses momentary heat from a light source to excite acoustic waves. Laser Imaging Systems of Punta Gorda, FL, developed the idea of photoacoustic leak detection. Dowling worked with Ford in developing leak localization as part of a team that was put together by the National Center for Manufacturing Sciences. Once a leak is sensed, a technique originally developed for a US Navy underwater acoustics program deploys to pinpoint its place. Vertical location is known already. Vacuum Instrument and Laser Imaging Systems are building the alpha prototype now.
