Resolution and apodization in images generated by twin photons

Abstract

In this work, we studied theoretically the image formation of an object when illuminated by at least one of the photons generated by the process of spontaneous parametric down-conversion (SPDC). In the process of SPDC, a pump (p) laser beam incident upon a nonlinear crystal creates a pair of photons, usually called signal (s) and idler (i). The number of detected coincident photons is proportional to the spatial quantum fourth-order correlation function C(rs,ri), calculated at the detectors transverse positions ri and rs. The light state |Ψ〉 generated by SPDC is written in the paraxial, monochromatic (∆ ωj(frequency bandwidth)<< ωj (frequency), j = s, i, p), and thin crystal approximation. All information about the object and the lenses are contained in the signal and idler electric field operators. The fourth-order correlation function can be rewritten as C=|g(rs,ri)|2 where g(rs,ri) is the probability amplitude for detecting the signal and idler photons at the image plane at transverse positions rs and ri, respectively.
