[0002] In related technologies, the acceleration sensor based on Newton's second law is usually used to obtain the acceleration of the measured object, and the acceleration sensor based on Newton's second law is generally only used to obtain the acceleration of the measured object. Therefore, the acceleration sensor based on Newton's second law The function of the acceleration sensor based on Newton’s second law is relatively simple, and the application scene is also relatively single, which greatly reduces the user’s experience. Moreover, the production cost of the acceleration sensor based on Newton’s second law is relatively high. At the same time, the acceleration of the measured object Detection accuracy is not high enough

The invention discloses an acceleration sensor, and an acceleration measuring device and method. The acceleration sensor comprises an imager, a liquid crystal lens arranged in front of the imager, anda controller. The controller is used for controlling voltages applied to the liquid crystal lens, acquiring images of a target object under different voltages by the imager, digitizing the images ofthe target object at different voltages to generate digitized information, determining implementation of first imaging focusing, second imaging focusing, third imaging focusing, and fourth imaging focusing on the target object by the liquid crystal lens based on the digitized information, acquiring a first focus voltage, a second focus voltage, a third focus voltage, and a fourth focus voltage based on the first to fourth imaging focusing, and calculating the acceleration based on the first focus voltage to the fourth focus voltage. According to the acceleration sensor, the accelerated speed of the measured object can be calculated accurately; the production cost is low and the functionality of the acceleration sensor is improved; the application range is widened; and the user experience is improved.
Description
technical field [0001] The invention relates to the technical field of acceleration sensors, in particular to an acceleration sensor, an acceleration measurement device and an acceleration measurement method. Background technique [0002] In related technologies, the acceleration sensor based on Newton's second law is usually used to obtain the acceleration of the measured object, and the acceleration sensor based on Newton's second law is generally only used to obtain the acceleration of the measured object.
