Adaptive single-pixel imaging through turbid media
Optica Publishing Group (2022-07-11)We present a system for imaging objects through non-homogeneous scattering media that works in an adaptive way by combining diffuse optical imaging (DOI) and single-pixel imaging (SPI) techniques. The experimental results ... -
Analysis of practical fractional vortex beams at far field
Elsevier ScienceDirect (2022-07-20)The subject of calculating the topological charge (TC) or vortex strength of optical vortices has generated divided opinions among scientists. This is due to the fact that proper analytical results are hard to support from ...

Dynamic freeform diffractive lens
Optica Publishing Group (2023-03-31)In the framework of the scalar theory of diffraction a surface-pixeled convergent lens for arbitrary amplitude and phase modulation along the depth of focus is introduced. This complex diffractive lens is computer-generated ... -
Dynamics of Fractional Vortex Beams at Fraunhofer Diffraction Zone
MDPI (2022-07-09)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. In ...

Single-pixel imaging with Fourier filtering: application to vision through scattering media
Optical Society of America (2019-02-01)We present a novel approach for imaging through scattering media that combines the principles of Fourier spatial filtering and single-pixel imaging. We compare the performance of our single-pixel imaging setup with that ...
