N. Korneev et S. Stepanov, MEASUREMENT OF DIFFERENT COMPONENTS OF VIBRATIONS IN SPECKLE REFERENCELESS CONFIGURATION USING ADAPTIVE PHOTODETECTORS, Optics communications, 115(1-2), 1995, pp. 35-39
We report application of adaptive photodetectors based on non-steady-s
tate photoEMF combined with speckle technique for measurement of in- a
nd out-of-plane vibration components for real, diffusely scattering ob
jects. The technique allows real-time measurements of vibrations with
amplitudes much lower than the speckle diameter.
