Decoupling the x, y and z displacement components in a rotating disc using three-dimensional pulsed digital holography

摘要

Three-dimensional twin-pulsed digital holography is used to separate the x, y and z displacement components in a rotating disc. The technique is able to distinguish the rotation and displacement movement along the xy plane from the out-of-plane z displacement. The results show that three-dimensional twin-pulsed digital holography may be used to derotate the object by combining information from three different illumination positions.
