主  题:object identification orbital angular momentum random light remote sensing second-order correlation 

摘      要:Photons that are entangled or correlated in orbital angular momentum have been extensively used for remote sensing,object identification and *** has recently been demonstrated that intensity fluctuations give rise to the formation of correlations in the orbital angular momentum components and angular positions of random *** we demonstrate that the spatial signatures and phase information of an object with rotational symmetries can be identified using classical orbital angular momentum correlations in random *** Fourier components imprinted in the digital spiral spectrum of the object,as measured through intensity correlations,unveil its spatial and phase *** similarities with conventional compressive sensing protocols that exploit sparsity to reduce the number of measurements required to reconstruct a signal,our technique allows sensing of an object with fewer measurements than other schemes that use pixel-by-pixel *** remarkable advantage of our technique is that it does not require the preparation of fragile quantum states of light and operates at both low-and high-light *** addition,our technique is robust against environmental noise,a fundamental feature of any realistic scheme for remote sensing.
