摘要：

An interferometric method of measuring the complex piezoelectric constants of crystals is described. A small interferometer was constructed in which a mirror and a half-mirror were separated by two spacers made of sample crystal.By using a PIN-photodiode and a lock-in amplifier a change in sample length as small as 0.01 Å due to the converse piezoelectric effect was detected. Since the mechanical resonance frequency of the interferometer was as high as 70 200 kHz, measurement of the piezoelectric constant was possible at any frequency in a range from 200 Hz to about 50 kHz. The results are shown for the measurements of d11of quartz and d22of ferroelectric AgNa(NO2)2. © 1979 IOP Publishing Ltd.
