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

Undersampled digital holography
Optics Express, 2009 Acceptable signal recovery of the band-pass signals typically used in the off-axis digital holography systems is possible in the undersampling conditions. A typical system is considered in which the angle between two beams represents a variable parameter.
