Enhancement of spatial resolution of ghost imaging via localizing and thresholding
Yunlong Wang, Yingnan Zhou, Shaoxiong Wang +5
In ghost imaging scheme, an illuminated light is split into test and reference beams which pass through two different optical systems respectively and an image is constructed by th…
An experimental measurement of the topological charge of orbital angular momentum beams through weak measurement
Jing Zhu, Pei Zhang, Qichang Li +7
As a special experimental technique, weak measurement extracts very little information about the measured system and will not cause the measured state collapse. When coupling the o…
Spatial sub-Rayleigh imaging analysis via speckle laser illumination
Yunlong Wang, Feiran Wang, Ruifeng Liu +4
It is commonly accepted that optical sub-Rayleigh imaging has potential application in many fields. In this Letter, by confining the divergence of the optical field, as well as the…
Measuring mode indices of a partially coherent vortex beam with HBT type experiment
Ruifeng Liu, Feiran Wang, Dongxu Chen +5
It is known that the cross-correlation function (CCF) of a partially coherent vortex (PCV) beam shows a robust link with the radial and azimuthal mode indices. However, the previou…
Evaluating Laguerre-Gaussian beams with an invariant parameter
Junling Long, Ruifeng Liu, Yunlong Wang +4
We define a new parameter about Laguerre-Gaussian (LG) beams, named , which is only related to mode indices and . This parameter is able to both evaluate and dist…
Characterizing vortex beam with angular-double-slit interference
Ruifeng Liu, Junling Long, Feiran Wang +4
The Fraunhofer diffraction intensity distribution of Laguerre-Gaussian beam is studied in an angular-double-slit interferometer. We demonstrate that the spiral phase structure of v…
