Four-channel volume holographic recording with linear polarization holography

Optics Letters, 2019
We report on four-channel volume holographic recording with linear polarization-sensitive holography. This technique is based on the null reconstruction effect (NRE) of linear polarization-sensitive holography, which means the diffraction efficiency ...

Volume holography-based abrupt autofocusing beam.

Applied Optics, 2023
Volume holographic elements are excellent at shaping high-quality spatial and spectral modes. Many microscopy and laser-tissue interaction applications require precise delivery of optical energy at specific sites without affecting the peripheral regions.

Simultaneous control of 3D volume speckle field and 3D holography through biological tissue

BiOS, 2023
Formation of complex light structures and three-dimensional complex holography through turbid media is a challenging task due to random variation in refractive index, scattering of light, and formation of speckle noise field.

Digital volume reflection holography

OPTO, 2022
Holography is the recording of the interference pattern of a reference and light reflected from or transmitted through an 3D object. In conventional digital holography, the interference intensity pattern is recorded on a digital camera.
