Diffraction from deformed volume holograms: perturbation theory approach [PDF]

, 2005
We derive the response of a volume grating to arbitrary small deformations, using a perturbative approach. This result is of interest for two applications: (a) when a deformation is undesirable and one seeks to minimize the diffracted field's sensitivity

Digital Holography Interferometry for Refractive Index Characterization and Temperature Mapping of Aqueous Solutions at Supercooled Temperatures

Laser &Photonics Reviews, Volume 19, Issue 9, May 6, 2025.
Digital holography interferometry (DHI) is used for thermal imaging and characterization of supercooled liquids. This work details a custom DHI platform with a thermoelectric cooling system capable of two‐dimensional temperature mapping and refractive index measurement of various aqueous solutions.

Holographic microscopy for the three-dimensional exploration of light scattering from gold nanomarkers in biological media

, 2011
The 3D structure of light scattering from dark-field illuminated live 3T3 cells marked with 40 nm gold nanomarkers is explored. For this purpose, we use a high resolution holographic microscope combining the off-axis heterodyne geometry and the phase ...

Imaging of a vibrating object by Sideband Digital Holography [PDF]

, 2009
We obtain quantitative measurements of the oscillation amplitude of vibrating objects by using sideband digital holography. The frequency sidebands on the light scattered by the object, shifted by n times the vibration frequency, are selectively detected

Polarization‐Controlled Diffractions of Submicron Pillar Arrays of Azo Molecular Glass for Image Recording and Reconstruction

Advanced Photonics Research, Volume 6, Issue 3, March 2025.
Submicron pillar array of an azo molecular glass (IA‐Chol) is used as media for polarization recording, which is achieved through directional pillar deformations induced by the illumination. The pillar arrays generate different diffracted waves upon the polarizations of the incident beams used for recording and image reconstruction.

Pulsatile microvascular blood flow imaging by short-time Fourier transform analysis of ultrafast laser holographic interferometry [PDF]

, 2015
We report on wide-field imaging of pulsatile microvascular blood flow in the exposed cerebral cortex of a mouse by holographic interferometry. We recorded interferograms of laser light backscattered by the tissue, beating against an off-axis reference ...

Complete Mode Spectrum Decomposition of Complex‐Structured Light by Computer‐Generated Holography

Advanced Photonics Research, Volume 6, Issue 2, February 2025.
In this article, a new optical method based on self‐interference is proposed to completely decompose the eigenmode spectrum of complex‐structured light. A diffractive optical method is designed and validated to extract the complete information of complex‐structured light fields composed with eigenmode superposition states, including the order of ...
