Abstract:We discuss a possibility of acieving sub-diffraction-limited resolution in coherent optical imaging using multimode squeezed light. For this purpose, we formulate a quantum theory of superresolution for object reconstruction in terms of prolate spheroidal functions. We derive the expression for ultimate resolution limit in the reconstructed object using an illumination of the full object plane by a multimode squeezed vacuum. We show taht the gain in superresolution using multimode squeezed light is maximum when the Shannon number S of the imaging system is smaller than unity. This situation is realized, for example, in sacnning microscopy. We present some preliminary numerical simulations aiming to demonstrate the feasibility of significant superresolution for S<1.
