Title:
MOMENTUM DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/029929
Kind Code:
A1
Abstract:
This momentum detection device has a vibrating body and a drive control unit for driving the vibrating body. The drive control unit samples a drive detection signal expressing displacement in the driving direction of the vibrating body at a first clock; generates the first clock on the basis of the sampled drive detection signal such that the length of each period varies; and applies a drive signal having a period of the same length as the total length of a prescribed number of periods, greater than or equal to two, of the first clock to the vibrating body for the purpose of driving the vibrating body.
