Abstract
The optimization of ultrasonic pulse shape by digitally generated excitation functions is demonstrated. Experiments show correspondence of objective function and easured pulse shape. Shortening of pulses down to 1/5 of "natural" -20 dB idth was achieved. The enhanced axial resolution can be useful in nondestructive testing and medical diagnosis with ultrasonics.
