Abstract
An acoustic probe and a method for making the same. The probe includes a novel interconnection network consisting of two portions, i.e., a first portion in which M.times.N conductive paths have a section contacting M.times.N piezoelectric transducers and are arranged at a pitch (P.sub.N) in a direction (D.sub.x) and at a pitch (P.sub.M) in direction (D.sub.y) within the acoustic absorption material; and a second portion in which the M.times.N conductive paths are arranged on M dielectric substrates spaced apart at a pitch (P'.sub.M) and each provided with N paths are arranged at a pitch (P'.sub.N). A method for making the acoustic probe is also disclosed. The dielectric substrates may advantageously be flexible printed circuits optionally including chips.
