Spectral analysis of amplitude and phase echoes in picosecond ultrasonics for strain pulse shape determination
We introduce a spectral analysis method in picosecond ultrasonics to derive strain pulse shapes in a opaque sample with known optical properties. The method makes use of both the amplitude and phase of optical transient relative reflectance changes obtained, for example, by interferometry. We demons...
