Title:
ACCELEROMETER
Document Type and Number:
WIPO Patent Application WO/2023/201936
Kind Code:
A1
Abstract:
An accelerometer, relating to the technical field of inertia measurement instruments, and comprising: a laser interferometer, an instrument head, and an acceleration resolving module. The instrument head comprises: a housing (1), a mass block (2), and an elastic support member (3); the mass block (2) is arranged inside the housing (1), and the mass block (2) is connected to the housing (1) by means of the elastic support member (3); the housing (1) is fixedly connected to an object to be tested; the laser interferometer is used for generating reference light and measurement light; the measurement light is transmitted to the interior of the housing (1) by means of an optical fiber (9), and is emitted to the surface of the mass block (2); the surface of the mass block (2) is used for reflecting measurement light to form reflected light; the laser interferometer is further used for receiving the reflected light and making the reflected light interfere with the reference light to form interference light; the laser interferometer is further used for converting the interference light into an interference signal and sending the interference signal to the acceleration resolving module for resolving so as to obtain an acceleration value of the object.
