Abstract

We consider the inverse scattering problem that arises in two-photon quantum imaging with interferometric measurements. We show that the two-point correlation function of the field contains information about the scattering medium at a spatial frequency of twice the Rayleigh bandwidth. The linearized inverse problem, however, yields reconstructions with a resolution of λ/2, where λ is the wavelength of light.

摘要

我们考虑了在具有干涉测量的双光子量子成象中出现的逆散射问题。我们表明，场的两点相关函数包含了关于散射介质的信息，其空间频率是瑞利带宽的两倍。然而，线性化的逆问题得到的重建结果的分辨率为 λ/2，其中 λ 是光的波长。
