We present an integrated optical system for three-dimensional (3D) imaging of micrometer-sized samples, while immobilizing and manipulating the samples by means of an optical fiber trap.

Optical interferometry and digital holography methods are accurate and effective tools used to achieve this task. In this chapter, we illustrate the application of different types of optical interference on conven-tional, polarizing maintaining and thick optical fibers.

The analysis and demonstration of a holographic coupler for single-mode optical fibers and cables is discussed. The holographic coupler is composed of two holographic windows. The holographic window is rigidly attached to the cable end. The coupling between windows proceeds by …

Mar 21, 2021 · The technique, named single-element reflective digital holographic microscopy (SER-DHM), enables QPI and topography analysis of reflective/opaque objects using a single-shot operation principle. SER-DHM is experimentally validated …

We design and establish a multi-resolution digital holographic microscope with optical fiber. The laser passes through the optical fiber coupler and the optical fiber splitter to form the illumination light wave and the reference light wave respectively.

Significance: Lensless digital inline holographic microscopy (LDIHM) is an emerg-ing quantitative phase imaging modality that uses advanced computational methods for phase retrieval from the interference pattern.

The dimensions and refractive index of a partially stripped optical fibre are evaluated by means of digital holographic microscopy. A recently introduced procedure for decoupling the information about the topography and refractive index from the phase information is employed for fully characterizing a multimode optical fibre.

May 1, 2021 · In summary, we have modified a commercially available pathology microscope into an off axis transmission DHM system for 3-dimensional imaging by adding two optical modules which are connected to two arms of a laser coupled 1 × 2 fiber coupler in an M-Z configuration.

In this paper, we report three-dimensional(3D) measurement results of structural parameters of fusion spliced optical fibers using digital holographic microtomography. A holographic setup in microscopy configuration with the sample-fixed and setup-rotating scheme is established. A series of holograms is recorded from various incident angles. …
