Multi-Object Deep-Field Digital Holographic Imaging Based on Inverse Cross-Correlation
Applied Sciences, 2023 To address the complexity of small or unique reconstruction distances in digital holography, we propose an inverse cross-correlation-based algorithm for the digital holographic imaging of multiplanar objects with a large depth of field. In this method, a

Imaging of a vibrating object by Sideband Digital Holography [PDF]
, 2009 We obtain quantitative measurements of the oscillation amplitude of vibrating objects by using sideband digital holography. The frequency sidebands on the light scattered by the object, shifted by n times the vibration frequency, are selectively detected
