Abstract
PURPOSE:To simplify constitution by supplying signals, generated by respective element of an array transducer by sensing, to various halfway points of a delay line and by extracting from its terminal. CONSTITUTION:Respective reflected wave signals from individual elements of array transducer TD are supplied to respective halfway points of delay line DL via corresponding pre-amplifiers (e). The signals supplied to respective places of delay line DL are shifted in phase according to the distance between respective supply points and both terminals of delay line DL and input to amplifiers A1 and A2. Consequently, the reflected waves are made into one and from amplifier A1 or A2, a composite reflected wave signal is obtained via switch S.
