title = "Rotational Doppler detection with Gaussian light mode emitter",
abstract = "Rotational Doppler effect has been recognized as a strongly robust technique for rotational body detection. Current consensus shows that rotational Doppler detection requires orbital angular momentum (OAM) manipulation and emission. Here, we challenge such popular belief by Gaussian mode emitter without expensive OAM modulator. Through probing beating frequency between two OAM eigenmodes within scattered multiple modes, we can measure rotational frequency of non-cooperative targets, and thus can be employed to specific target identification. Experiments demonstrate the good agreement with theoretical analysis. Our methodology and findings may be used to astronomical observation, meteorological monitoring, unknown celestial body detection and industrial applications.",
