摘要：

The cross calibration of two optical detection techniques is described for the monitoring of laser-generated Lamb waves. Measurements of Lamb waves using an optical beam deflection technique are compared with those using a Michelson interferometer technique. Analysis shows that phase changes in acoustic waveforms relate to the physical characteristics of the two detection schemes. Results are self-consistent, and show that the beam deflection technique is capable of providing quantitative waveform analysis.
