Vibration analysis of membrane by time average in-line digital holographic interferometry

Vibration analysis of membrane by time average in-line digital holographic interferometry

In this paper, in-line digital holography is combined with time average method and applied for vibration analysis of an aluminum membrane. The numerically reconstructed wave from time average holograms contains information of mode shape and mean deformation of the vibrating objects. At lower amplitu...
