Radial modal transitions of Laguerre-Gauss modes during parametric upconversion: towards the full-field selection rule of spatial modes
Hai-Jun Wu, Li-Wei Mao, Yuan-Jie Yang +4
Optical orbital angular momentum transformation and corresponding azimuthal-mode selection rules have been studied exhaustively for various nonlinear optical interactions. However,…
Full characterization of spin-orbit coupled photons via spatial-Stokes measurement
Bing-Shi Yu, Hai-Jun Wu, Hao-Ran Yang +4
Characterization and analysis of spin-orbit coupled (SOC) states, as a measurement problem, play a vital role in research on the modern optics and photonics based on structured lig…
Does the structure of light influence the speckle size?
Xiao-Bo Hu, Meng-Xuan Dong, Zhi-Han Zhu +2
It is well known that when a laser is reflected from a rough surface or transmitted through a diffusive medium, a speckle pattern will be formed at a given observation plane. Speck…
In-situ detecting cooperative-target's speed and rotation inertia using structured light
Xiao-Bo Hu, Bo-Zhao, Zhi-Han Zhu +2
Laser remote sensing represents a powerful tool that enables the accurate measurement of the speed of moving targets. Crucially, most sensing techniques are 2-Dimensional and only…
