摘要：
A measurement method of magnetostriction with a laser displacement meter on the market has been compared with the other optical method using laser Doppler vibrometer. In the measurement, the frame to excite the specimen is divided into three parts to fix the specimen, and the phase difference must be adjusted. It is shown that the lambda(p-p) characteristics measured by laser displacement meter have good agreement with the other method. (C) 2002 Published by Elsevier Science B.V.
