Digital holographic microscopy with physical phase compensation.
TL;DR: An optical configuration for digital holographic microscopy using a single-cube beam splitter in a nonconventional configuration so as to both split and combine a diverging spherical wavefront emerging from a microscope objective.

Parallel two-step phase-shifting point-diffraction interferometry for microscopy based on a pair of cube beamsplitters
Peng Gao,Baoli Yao,Junwei Min,Rongli Guo,Juanjuan Zheng,Tong Ye,Irina Harder,Vanusch Nercissian,Klaus Mantel +8 more
TL;DR: Based on the proposed configuration, slightly-off-axis interferometry for microscopy is performed, which suppresses dc term by subtracting the two phase-shifting holograms from each other.
Journal ArticleDOI
Single-shot slightly off-axis digital holographic microscopy with add-on module based on beamsplitter cube.
TL;DR: The proposed approach provides an optimized use of the imaging system, in terms of the space-bandwidth product, in comparison with off-axis configuration; allows the analysis of fast-dynamic events, owing to its single-shot capability when compared with on-axis arrangement; and becomes easily implementable in conventional white-light microscopes for upgrading them into holographic microscopeopes for QPI.
Journal ArticleDOI
Transmission digital holographic microscopy based on a beam-splitter cube interferometer
TL;DR: The novelty of the proposed configuration is its simplicity, minimal number of optical elements, insensitivity to vibration, and its inherent capability to compensate for the phase curvature that results from the illuminating wavefront in the case of microscopic samples.

A writing technique for long fiber Bragg gratings with complex reflectivity profiles
TL;DR: In this article, the authors developed and demonstrated a novel technique to manufacture very long gratings with a nearly arbitrary reflectivity profile, based upon writing a set of consecutive subgratings with interferometric control of the relative position of each subgrating.

Robust one-beam interferometer with phase-delay control.
TL;DR: In this paper, a robust one-beam interferometer with external phase-delay control is described, where the two arms are together in one collimated beam, and an additional phase delay is introduced by application of an electrical current to the Faraday rotator or by rotation of the polarizer (the latter being of topological origin).
