Polarization sensing in digital holographic microscopy [PDF]
2020 IEEE Aerospace Conference, 2020 Digital holographic microscopy is well suited to the search for microbial species due in part to its intrinsic stability, volumetric imaging capability, and sensitivity to very dilute samples. This is all done with a system having no moving parts, making it additionally attractive for flight instrumentation.

Superesolution in digital holographic microscopy
2011 10th Euro-American Workshop on Information Optics, 2011In this contribution, we address with the possibility to overcome the limited resolving power of imaging systems beyond the limit imposed by Abbe's diffraction theory. We first review the mathematical foundations underlying superresolution (SR) from an information theory point of view and then we focus on two multiplexing approaches in digital ...

Robust autofocus for digital-holographic microscopy
OSA Imaging and Applied Optics Congress 2021 (3D, COSI, DH, ISA, pcAOP), 2021A new method to achieve autofocus in digital holography is proposed. It is based on the insertion of calibrated objects in the sample and the use of a robust algorithm to locate these objects.

Angular spectrum matching for digital holographic microscopy under extremely low light conditions.
Optics Letters, 2021Digital holographic microscopy (DHM) is a future three-dimensional (3D) microscopy due to its high-resolution and high-precision 3D images. Thus, it is getting attention in bioinformatics, semiconductor defect detection, etc.

Immersion digital in-line holographic microscopy
Optics Letters, 2006Digital in-line holographic microscopy is a promising new tool for high resolution imaging. We demonstrate, by using latex beads, that a considerable increase in numerical aperture, and, therefore, resolution can be achieved if the space between a source and a CCD camera chip is filled with a high refractive index medium.

Optical Tomography by Digital Holographic Microscopy
Novel Optical Instrumentation for Biomedical Applications IV, 2009Optical tomography provides three-dimensional data of the measured specimen, while quantitative phase imaging enables measuring the induced phase-shifts. Combining those two technologies makes possible to get three-dimensional refractive index reconstruction.

In-line digital holographic imaging in volume holographic microscopy
Optics Letters, 2015A dual-plane in-line digital holographic imaging method incorporating volume holographic microscopy (VHM) is presented to reconstruct objects in a single shot while eliminating zero-order and twin-image diffracted waves. The proposed imaging method is configured such that information from different axial planes is acquired simultaneously using ...
