Wavelength Routing for Transparent Optical Wireless Communications Based on Volume Holography

Conference on Lasers and Electro-Optics
A 17-Gbit/s wavelength routing system using volume holography beam-steering for all-optical infrared networking is presented. Polarization-independent demultiplexing of four channels is demonstrated with a loss of 14 dB, and crosstalk suppression of 15 ...

Image processing using volume holography

OPTO
The application of volume gratings for image processing operations such as edge enhancement is reviewed, along with its suitability for ultra-high-definition displays. In particular, holographically written volume reflection gratings in a photorefractive

Measurement of Cell Volume Using In-Line Digital Holography.

Microscopy, 2020
The measurement of the volume of blood cells is important for clinical diagnosis and patient management. While digital holography microscopy (DHM) has been used to obtain such information, previous off-axis setups usually involve a separated reference ...

Imaging through distributed-volume aberrations using single-shot digital holography.

Journal of The Optical Society of America A-optics Image Science and Vision, 2019
This paper explores the use of single-shot digital holography data and a novel algorithm, referred to as multiplane iterative reconstruction (MIR), for imaging through distributed-volume aberrations. Such aberrations result in a linear, shift-varying or "

Hyperspectral holography and volume Denisyuk holograms

Optics + Optoelectronics, 2019
Registration of two types of digital holograms is considered: digital hyperspectral holograms and Denisyuk volume holograms (holograms in colliding beams). Hyperspectral holograms are considered as an analogue of thin holograms, in which zero order and a

Measurements of Dimension and Morphology of Solid Particles Volume With Digital In-Line Holography

Volume 4: Fluid Measurement and Instrumentation; Micro and Nano Fluid Dynamics, 2019
Digital in-line holography (DIH) has been applied to measure the 3D position of objects in a variety of applications, including bubbles and droplets in multi-phase flows, tracking particles in turbulence flows, etc.

Acoustic holography in biomedical applications

Physics in Medicine and Biology
Acoustic holography can be used to construct an arbitrary wavefront at a desired 2D plane or 3D volume by beam shaping an emitted field and is a relatively new technique in the field of biomedical applications.
