ABSTRACT:
The number of transducers in the scanning of an ultrasonic field from an object is reduced by providing ultrasonic collectors at spaced apart locations in the medium and transmitting the ultrasonic waves which are collected to a transducer through waveguides or paths having different transit times. The waveguides can be individually of different lengths or can be of equal length and terminate at different distances along a common collecting waveguide.
