Abstract
A pulsed laser photoacoustic measurement technique, utilising laser di ode sources, has been developed for the detection of oil contamination in water. The measurement of oil-contaminated water samples of oil co ncentration ranging from 0 to 900 mg l(-1) is presented. Also reported are results from a theoretical modelling, which includes several expe rimental factors important to the photoacoustic sensor design for this type of application.
