PROBLEM TO BE SOLVED: To improve detection accuracy when detecting the displacement of an object in a non-contact manner.SOLUTION: An object displacement detection device for detecting the displacement of an object to be detected based on a transmission wave transmitted to the object to be detected and a reflection wave of the transmission wave by the object to be detected includes: a displacement amount calculation section for calculating the displacement of the object to be detected based on the transmission wave and the reflection wave; and a displacement component information extraction section for acquiring the displacement of the object to be detected based on the relationship between the time when an inflection point of a displacement wave form acquired based on the displacement calculated by the displacement amount calculation section occurs, and the displacement cycle of the object to be detected. |
