  • Method and device for improved measurement of ultrasound propagation time difference
    Publication number: 20120266676
    Abstract: A method for measuring a propagation time difference includes: sending a transmitted ultrasound pulse, which is provided with a transmission reference instant and which includes an envelope and a carrier frequency, into a spatial region and receiving a received ultrasound pulse that corresponds to the transmitted ultrasound pulse transmitted. A coarse time difference is provided by comparing the transmission reference instant with an envelope of the received ultrasound pulse, for at least two cycles of transmission/reception in opposite directions of transmission. A fine time difference is provided by comparing the transmission reference instant with an instantaneous variation of the received ultrasound pulse, for the at least two cycles of transmission/reception in opposite directions of transmission.
