The presence of off-axis tilt and Petzval curvature, two of the lowest-order off-axis Seidel aberrations, are shown to improve the Fisher information of two-point separation estimation in an incoherent imaging system compared to an aberration-free system. Our results show that the practical localization advantages of modal imaging techniques within the field of quantum-inspired superresolution can be achieved with direct imaging measurement schemes alone.
存在离轴倾斜和佩兹瓦尔曲率这两种低阶离轴赛德尔像差，与无像差系统相比，它们提高了非相干成像系统中两点分离估计的 Fisher 信息。我们的结果表明，仅通过直接成像测量方案，就可以在量子启发的超分辨率领域中实现模态成像技术的实际定位优势。
