Experimental evidence of high-resolution ghost imaging and ghost diffraction with classical thermal light

arXiv:quant-ph/0408021 · doi:10.1103/PhysRevLett.94.183602

Abstract

High-resolution ghost image and ghost diffraction experiments are performed by using a single source of thermal-like speckle light divided by a beam splitter. Passing from the image to the diffraction result solely relies on changing the optical setup in the reference arm, while leaving untouched the object arm. The product of spatial resolutions of the ghost image and ghost diffraction experiments is shown to overcome a limit which was formerly thought to be achievable only with entangled photons.
