PCT No. PCT/FR96/01650 Sec. 371 Date Jul. 2, 1997 Sec. 102(e) Date Jul. 2, 1997 PCT Filed Oct. 22, 1996 PCT Pub. No. WO97/17145 PCT Pub. Date May 15, 1997An 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 MxN conductive paths have a section contacting MxN piezoelectric transducers and are arranged at a pitch (PN) in a direction (Dx) and at a pitch (PM) in direction (Dy) within the acoustic absorption material; and a second portion in which the MxN conductive paths are arranged on M dielectric substrates spaced apart at a pitch (P'M) and each provided with N paths are arranged at a pitch (P'N). A method for making the acoustic probe is also disclosed. The dielectric substrates may advantageously be flexible printed circuits optionally including chips. |
