摘要

An interferometric method for measuring vibration displacement and acceleration in the 800 Hz - 10 kHz frequency range is described and experimentally tested. Our experimental setup is based on the Twyman-Green interferometer and we were able to measure vibration displacements of 0.12 and 0.27 urn. Depending on frequency, accelerations in the range 1.52 - 10.75 m/s2 were obtained.
