Abstract  Abstract

A kind of Nonlinear Dynamic focusing controlling method, including: 1) there is the minimum length in the minimum length scan line with greatest length as initial position, and in this scan line, configure focus point;2) calculate half depth of focus of focus point, this initial position is added the position that half depth of focus of this focus point is positioned in scan line as this focus point;3) using position that this focus point is positioned in this scan line to the direction of this greatest length plus half depth of focus of this focus point as the calculating original position of next focus point;4) judge that the calculating original position of next focus point, whether more than this greatest length, if it is not, then replace this initial position with the calculating original position of this next focus point, repeats step 2) to 3), the most then terminate to calculate;Wherein, those focus position in this scan line according to some wave source spread functions shift invariant characteristic and in nonlinear Distribution.Accordingly, can efficiently configure focus point and reduction has the computational complexity of imaging system of array energy transducer.
