We present a theoretical model to sufficiently investigate the optical rotational Doppler effect based on modal expansion method. We find that the frequency shift content is only determined by the surface of spinning object and the reduced Doppler shift is linear to the difference of mode index between input and output orbital angular momentum (OAM) light, and linear to the rotating speed of spinning object as well. An experiment is carried out to verify the theoretical model. We explicitly… Expand
Influence of lateral misalignment on the optical rotational Doppler effect.
TLDR
This paper investigates the influence of lateral misalignment, i.e., the distance between the beam axis of a probe light and the rotationaxis of a spinning object, on the rotational Doppler effect and deduces the generalized formula of rotational doppler shift based on a local scattering model.

Detection of angular acceleration based on optical rotational Doppler effect.
TLDR
A time-frequency analysis method is proposed to study the evolution of the angular velocity in time and the experimental results of different angular accelerations of the rotator are consistent with expectations. Expand

Detection of spinning objects at oblique light incidence using the optical rotational Doppler effect.
TLDR
The analytic results indicate that even if the rotational axis of the spinning object is oriented at a specific tilt angle relative to the light propagation direction, theRotational speed can still be extracted from an asymmetrically broadened Doppler signal. Expand

Through theoretical research results, a novel method of measuring rotation velocity is proposed, with the light spot completely deviated out of the rotation center, which is of great significance to the remote detection of non-cooperative rotation object. Expand

Optical angular momentum in a rotating frame.
TLDR
It is shown that the OAM of the incident beam is not affected by the rotating observer and that the measured wavelength is shifted by a factor equal and opposite to that of the frequency shift induced by the rotational Doppler effect. 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.
