Special Issue on Digital Holographic 3D Imaging: Capture, Display, and Evaluation

ETRI Journal, 2019
Holography has been fascinating people for almost 70 years (since Gabor's invention in 1947) as a true three‐dimensional (3D) imaging technology that can replicate 3D scenes in free space.

Single-shot, simultaneous incoherent and holographic microscopy

In this work, we demonstrate single-shot, simultaneous recording and subsequent retrieval of one incoherent and two holographic (intensity and phase) images from the same camera frame.

Low-coherence off-axis digital holographic microscopy

, 2021
Usually, off-axis digital holographic microscopy requires a coherent light source in order to record a full-field hologram. Nevertheless, a LASER-based illumination leads to a non-negligible coherent noise, decreasing then the imaging quality.

Computational coherent superposition self-reference digital holographic microscopy for multiwavelength 3D information acquisition

JPhys Photonics
I propose a digital holographic microscopy technique in which complex amplitude distributions at multiple wavelengths are simultaneously obtained with a common-path self-reference interferometer and a monochrome image sensor.

Microsphere-assisted quantitative phase microscopy: a review

Light: Advanced Manufacturing
Light microscopes are the most widely used devices in life and material sciences that allow the study of the interaction of light with matter at a resolution better than that of the naked eye. Conventional microscopes translate the spatial differences in

Separation of overlapped particles in digital holographic microscopy

Optics Express, 2013
In this paper, we present a procedure to separate aggregates of overlapped particles in digital holograms, based on a focus plane analysis applied to each particle. The method can be applied either on phase or on amplitude objects, according that each object has a border in one focus plane. Numerical simulations are performed to quantify the robustness
