We investigate the evolution of Bessel–Gaussian (BG) optical beams in using the fractional Schr？dinger equation (FSE) without potential or with nonlocal nonlinear media, theor...
We present a novel and straightforward Fibonacci lens, which is created by binarizing and adding a spiral phase to its radial phase function. It is shown that this new element y...
This study presents a polarization grating based diffraction phase microscopy (PG-DPM) and its application in bio-imaging. Compared with traditional diffraction phase microscopy...
The obstacle of imaging through multimode fibers (MMFs) is encountered due to the fact that the inherent mode dispersion and mode coupling lead the output of the MMF to be scatt...
Photosensitivity in photo-thermo-refractive (PTR) glass can be triggered by UV and near-infrared fs laser irradiation. Here we focus on the nonlinear photochemical process trigg...
The accuracy of _2}$ cameras is significantly determined by the ability to obtain an accurate calibration. This work presents a real-time continuous calibration method...
