Title:
DISPLACEMENT MEASURING DEVICE
Document Type and Number:
Japanese Patent JP2021146952
Kind Code:
A
Abstract:
To provide a displacement measuring device which can eliminate routing of a complicated wiring for measuring a compression state (displacement) of a plurality of positions corresponding to a load.SOLUTION: A displacement detecting device 1 comprises: a plurality of reflection members 12 arranged on a detection target; a signal source 21 which transmits a wave of a prescribed frequency which can pass a human body, to each of the reflection members 12; a transmission antenna 22; a reception antenna 23 for receiving the wave which is reflected by each of the plurality of reflection members 12 and returns; a mixer 24; a distance calculating part 25 for calculating distance information to the plurality of reflection members 12 on the basis of time information until the transmitted wave returns; and a displacement distribution measuring part 30 for calculating a displacement amount of each reflection member 12 out of the plurality of reflection members, on the basis of the distance information.SELECTED DRAWING: Figure 1
