SENSING APPARATUS USING MULTIPLE ULTRASOUND PULSE SHAPES

摘要

A sensing apparatus comprising an ultrasound transceiver for transmitting ultrasound signals into a sample and receiving a resultant ultrasound reflection signal from the sample, a detector for processing signals received by the transceiver by comparing the received signal against a reference signal to generate a response signal, the response signal comprising values as a function of time that represent the strength of the match between the received signal and the reference signal at the respective time; and a driver capable of generating a plurality of pre-defined pulse templates.
