We discuss the ultimate limit imposed by quantum fluctuations of light for resolution of fine details in optical images. For this purpose, we extend in the quantum domain the classical analysis of the object reconstruction, or superresolution, in terms of prolate spheroidal function basis. 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 that the gain in resolution using multimode squeezed light is maximum when the Shannon number of the imaging system is close to unity.
我们讨论了光的量子涨落对光学图像中精细细节分辨率所施加的最终极限。为此，我们在量子领域扩展了基于长球函数基对物体重建（即超分辨率）的经典分析。我们通过用多模压缩真空对整个物体平面进行照明，推导出重建物体中最终分辨率极限的表达式。我们表明，当成像系统的香农数接近1时，使用多模压缩光获得的分辨率增益最大。
