The production of classically correlated beams suitable for coherent imaging was investigated using classical correlation of two beams obtained by splitting coherent thermal radiation. A formal analogy was also demonstrated between two classically correlated beams and two entangled beams produced by parametric down-conversion (PDC). It was observed that classical beams were spatially correlated in near field and in far field. The performance of a quasithermal and parametric down-conversion source were found to be similar using numerical simulations.

Abstract
The production of classically correlated beams suitable for coherent imaging was investigated using classical correlation of two beams obtained by splitting coherent thermal radiation. A formal analogy was also demonstrated between two classically correlated beams and two entangled beams produced by parametric down-conversion (PDC). It was observed that classical beams were spatially correlated in near field and in far field. The performance of a quasithermal and parametric down-conversion source were found to be similar using numerical simulations.File in questo prodotto:
