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 an 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 demon...
