Dual-Comb Hyperspectral Digital Holography [PDF]
Nature Photonics 15, 890-894 (2021), 2021 Holography has always held special appeal, for it is able to record and display spatial information in three dimensions. Here, we show how to augment the capabilities of digital holography by using a large number of narrow laser lines at precisely-defined optical frequencies simultaneously.

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.

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
