That is however not the case. For every transducer there is a significant random phase shift present. This will completely negate our effort to acheive a phased array. So we have to measure the phase shift of every transducer and incorporate this into the phase calculations. + ### Video Below is a video showing two ultrasonic arrays levitating a piece of styrofoam in an preprogrammed path.
