Abstract

A non-destructive elastic properties detection method based on 3×3 fiber-optic coupler based interferometer is proposed. The relationship of speed versus frequency components of surface acoustic wave (SAW) propagating through the surface of an object gives clues of its physical properties such as elasticity, density, and thickness, etc. In order to reliably observe the SAW signals of objects where physical contact is not allowed, we constructed an interferometer based on the fiber-optic coupler and measured the SAW signal. The performance of the system was verified with well-defined layer phantoms which were made in various structures and analyzed the elasticity and structure of the samples.
