Abstract

The invention discloses a displacement sensor, a displacement detection method and a displacement detection system, which are used for simplifying the structure and manufacturing difficulty of the displacement sensor. The embodiment of the invention provides a displacement sensor. The displacement sensor comprises a first substrate, a resonator located at one side of the first substrate, and an electromagnetic field generation part located at one side, deviating from the resonator, of the first substrate, the opening resonator comprises a conductor ring; the conductor ring is provided with an opening; the resonator is used for bearing an object to be measured, is fixed relative to the position of the object to be measured, and slides on the surface parallel to the plane where the first substrate is located.

Description

technical field [0001] The present application relates to the technical field of sensors, and in particular, to a displacement sensor, a displacement detection method and a displacement detection system. Background technique [0002] For scenarios that need to detect displacement in a small range, such as camera lens stabilization, production line alignment and positioning, etc., it is necessary to detect the displacement of objects to ensure that the position of the object is appropriate. [0003] In the prior art, the displacement of an object is usually detected by a displacement sensor. However, the displacement sensor is usually a sensor including an LC resonator or an optical displacement sensor, etc. The structure of the displacement sensor is complex and the preparation is difficult. SUMMARY OF THE INVENTION [0004] Embodiments of the present application provide a displacement sensor, a displacement detection method, and a displacement detection system, so as to ...
