Hello NDT experts, I would appreciate any info. on the possibility of an ultrasonic waveguide much like the optical waveguide used in medical endoscopes and remote cameras. My application is ultrasonic imaging, where due to high EM noise the receiving transducer array needs to be some distance away from the sample. A waveguide or standoff that would preserve the acoustic wavefront over say 5 inches distance would allow the receiving array to be placed remotely from the sample and still form images. Any suggestion's welcome, thanks for your attention.
