Dynamics of Fractional Vortex Beams at Fraunhofer Diffraction Zone
Photonics, 2022 Fractional vortex beams (FVBs) possess unique topological properties that are manifested in the vortex distribution. However, there are still discrepancies in the value of the vortex strength of FVBs at the far field.

Spatial light modulators [PDF]
Photoniques, 2020 Spatial Light Modulators (SLMs) are quasiplanar devices, allowing for the modulation of the amplitude, phase and polarization, or a combination of these parameters of an incident light beam according to the two spatial dimensions of the modulator. SLMs are employed in many different fields and are the subject of continuous technological development.

Concentric Perfect Optical Vortex Beam Generated by a Digital Micromirrors Device
IEEE Photonics Journal, 2017 We propose a kind of perfect optical vortex beam (POV) generated via Fourier transformation of Bessel-Gauss (BG) beams through encoding of the amplitude of the optical field with binary amplitude digital micromirrors device.

Non-Interferometric Tomography of Phase Objects Using Spatial Light Modulators
Journal of Imaging, 2016 Quantitative 3D phase retrieval techniques are based on either interferometric techniques such as holography or noninterferometric intensity-based techniques such as the transport of intensity equation (TIE).
