摘要：

A Michelson-based fibre optic interferometer was used to make absolute measurements of the sub-nanometer liquid surface displacements created by the photoacoustic process. This measurement system is both broad-band and non-contacting. Photoacoustic waves, generated using pulses from a Nd:YAG laser operating at 1.06 mum, were measured in methanol, water, and various concentration mixtures. The wave amplitude demonstrated a quadratic relationship with concentration.
