Abstract
Apparatus and method for optimizing an ultrasonic signal are provided, one of apparatus comprises, an ultrasonic signal sensing unit which transmits and receives an ultrasonic signal, a residual oscillation measurement unit which measures a first ringing time of the ultrasonic signal transmitted from the ultrasonic signal sensing unit, a comparison and calculation unit which compares the first ringing time with a pre-stored second ringing time and calculates a correction frequency based on the comparison result, an electrical damping pulse generation unit which generates an electrical damping pulse having the correction frequency and a control unit which controls the electrical damping pulse to be applied to the ultrasonic signal sensing unit.
