VIBRATION DETECTION ELEMENT, VIBRATION MEASURING DEVICE, AND VIBRATION MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a vibration detection element for detecting vibration in the noncontact state without laminating a reflection seal even on an object not having a characteristic for reflecting laser light, and taking out a sufficient signal from a received radio wave, and a vibration measuring device and a vibration measuring method for using properly the vibration detection element.

SOLUTION: A radio wave is transmitted to a measuring target object by a radio wave transmission means 2. A transmitted radio wave and a reflected radio wave are received by an antenna 4 arranged inside a radio wave reflection means 3 and near the radio wave transmission means 2, and a signal including information on phases of the transmitted radio wave and the reflected radio wave received by the antenna 4 is detected by a transistor 5.
