In this paper we propose a new method detecting both OAM and polarization state for a vector vortex beam using rotational Doppler effect. We show that this new approach measures both the absolute value of the topological charge and its sign. Also, the phase and the visibility of the intensity variance gives the polarization parameters of vector beam. We have also experimentally proved the feasibility of our method. This method solves the drawback in existing experimental schemes that they… Expand

Theoretical analysis and experimental verification on optical rotational Doppler effect.
TLDR
The theoretical model makes us better understand the physical processes of rotational Doppler effect, and thus has many related application fields, such as detection of rotating bodies, imaging of surface and measurement of OAM light. Expand
Vectorial Doppler metrology
TLDR
This work conducts a proof of principle experiment and successfully measure the rotational velocity (magnitude and direction) of a moving isotropic particle and opens the path to vectorial Doppler metrology for detection of universal motion vectors with vectorially structured light. Expand
Detection of a Spinning Object Using Light’s Orbital Angular Momentum
TLDR
Using twisted light, Lavery et al. detected rotation with an analogous angular Doppler shift, which may be useful for remote sensing and observational astronomy, and the multiplicative enhancement of the frequency shift may have applications for the remote detection of rotating bodies in both terrestrial and astronomical settings.

Observation of the rotational Doppler shift of a white-light, orbital-angular-momentum-carrying beam backscattered from a rotating body
We observe the rotational Doppler shift of an orbital angular momentum (OAM)-carrying white-light beam after it is backscattered from a rotating object. Unlike the well known linear shift, thisExpand
Vector Beam Polarization State Spectrum Analyzer
TLDR
It is shown that this system can be used as a vector beam polarization state spectrum analyzer, where both the topological charge and the state of polarization of an input vector beam can be simultaneously determined in a single experiment. Expand
Measurement of the topological charge and index of vortex vector optical fields with a space-variant half-wave plate.

This work presents a simple method to measure the topological charge and index of VVOFs by using a space-variant half-wave plate (SV-HWP). Expand
Polarization pattern of vector vortex beams generated by q-plates with different topological charges.
TLDR
The polarization topology of the vector beams emerging from a patterned birefringent liquid crystal plate with a topological charge q at its center is described and a tuned q=1/2-plate is used to generate cylindrical vector beams with radial or azimuthal polarizations. Expand
Trapping volume control in optical tweezers using cylindrical vector beams.
TLDR
It is shown that the additional degree of freedom present in CVBs allows us to control the optical trap strength and geometry by adjusting only the polarization of the trapping beam. Expand
Fiber propagation of vector modes.
TLDR
This work employs both dynamic and geometric phase control of light to produce radially modulated vector-vortex modes, the natural modes of optical fibers, and measures the modal cross-talk and non-separability decay during propagation using a vector modal decomposition set-up and tomography measurement.
