Diffraction Focal Position and Vector Diffraction Theory for Micro Holographic Storage Systems
Applied Sciences, 2014 In this study, we proposed a method to determine the optimal focal position for micro-holographic storage systems, using vector diffraction theory; the theory provides exact solutions when the numerical aperture (NA) exceeds 0.6.

Multidither coherent optical adaptive technique for deep tissue two-photon microscopy [PDF]
Journal of Innovative Optical Health Sciences, 2019 Two-photon microscopy normally suffers from the scattering of the tissue in biological imaging. Multidither coherent optical adaptive technique (COAT) can correct the scattered wavefront in parallel.

Highly Efficient Double-Layer Diffraction Microstructures Based on New Plastics and Molded Glasses
Photonics, 2021 Within the framework of rigorous diffraction theory, the maximum possible incidence angles of radiation on two-layer sawtooth relief-phase microstructures in the visible (0.4 ≤ λ ≤ 0.7 μm) spectral range are compared.

Aharonov–Bohm phase shifts induced by laser pulses [PDF]
, 2008 An experimentally accessible scalar Aharonov–Bohm (AB)-effect is proposed using a ponderomotive potential induced by a pulsed laser. This ponderomotive AB (PAB)-effect is unique in that the time-averaged description is classified as type-I, whereas the ...

On Localized "X-shaped" Superluminal Solutions to Maxwell Equations [PDF]
, 1998 In this paper we extend for the case of Maxwell equations the "X-shaped" solutions previously found in the case of scalar (e.g., acoustic) wave equations.

A Light-Ray Approach to Fractional Fourier Optics
Fractal and Fractional, 2023 A light ray in space is characterized by two vectors: (i) a transverse spatial vector associated with the point where the ray intersects a given spherical cap; (ii) an angular-frequency vector which defines the ray direction of propagation. Given a light
