The scanning laser interferometer (SLI) may be used in a variety of ways for gathering vibration data in the automotive field. The instrument itself may be treated as a steerable transducer which provides an output proportional to velocity in the same way that an accelerometer provides output proportional to acceleration. By combining the instrument with a 1/3 octave band analyser and a micro-computer, a system has been developed which enables large areas to be scanned automatically and vibration distributions plotted. Examples of results obtained from measurements on engines and vehicle bodywork are discussed.
