ABSTRACT:
A delay circuit for providing signal delay within an acoustic imaging system is provided. Reflected acoustic signals are transformed into electrical signals and are used to reproduce images of objects. Delay lines along the electrical signal path are used to focus the images compensating for asynchronism of electrical signals caused by variations in the length of acoustic signal paths.
