title: Measurement of Young's modulus in an elastic material using 3D digital holographic interferometry.
abstract: Digital holographic interferometry using three different illumination directions is applied to quantify in full field of view the deformation of an elastic membrane under a given vibration frequency. The technique allows the separation of the object microdisplacements components in the x, y, and z directions, and the resulting data is used to find the membrane Young's modulus. The latter was compared with the result obtained using the theory of thin plates for a clamped circular membrane under a uniformly distributed load, reaching a 95% agreement. Validation of the results between these methods shows the reliability of DHI to measure the mechanical properties of an elastic material.
