Tracking the kinematics of fast-moving objects is an important diagnostic tool for science and engineering. Existing optical methods include high-speed CCD/CMOS imaging, streak cameras, lidar, serial time-encoded imaging and sequentially timed all-optical mapping. Here, we demonstrate an entirely new approach to positional and directional sensing based on the concept of classical entanglement in vector beams of light. The measurement principle relies on the intrinsic correlations existing in…

It is demonstrated that the spatial signatures and phase information of an object with rotational symmetries can be identified using classical orbital angular momentum correlations in random light, and the technique is robust against environmental noise, a fundamental feature of any realistic scheme for remote sensing.
