论文摘要
本文介绍了统计处理（P场）的统计处理 - 一种波浪状的数量，表明时间平均辐照度的时间变化缓慢（最近引入了用于模型和描述非线（NLOS）成像（NLOS）成像以及通过扩散或散射量的成像的型号，并量化的型号均出现了一部分，这一数字均出现了一部分，并且量化了一部分，这一速率是迅速的，这是迅速的一部分。光载体。 Huygens样p场成像积分不描述出这种虚假信号，该积分假定光学不相互性是完全描述p场成像的必要条件（如Reza等人最近所示）。在本文中，我们估算了该虚假信号的预期幅度与P场成像系统内的部分粗糙度程度之间的关系。该处理使我们能够确定p场积分为不同程度的部分相干性提供的估计值的准确性，并允许将p场信号 - 噪声比定义为部分相干光载体的情况。对部分连贯性的研究还可以更好地将光圈粗糙度与P场噪声联系起来。
This paper presents a statistical treatment of phasor fields (P-fields) - a wave-like quantity denoting the slow temporal variations in time-averaged irradiance (which was recently introduced to model and describe non-line-of-sight (NLoS) imaging as well as imaging through diffuse or scattering apertures) - and quantifies the magnitude of a spurious signal which emerges due to a partial spatial coherence of the underlying optical carrier. This spurious signal is not described by the Huygens-like P-field imaging integral which assumes optical incoherence as a necessary condition to describe P-field imaging completely (as was shown by Reza etal. recently). In this paper, we estimate the relationship between the expected magnitude of this spurious signal and the degree of partial roughness within the P-field imaging system. The treatment allows us to determine the accuracy of the estimate provided by the P-field integral for varying degrees of partial coherence and allows to define a P-field signal-to-noise ratio as a figure-of-merit for the case of a partially coherent optical carrier. The study of partial coherence also enables to better relate aperture roughness to P-field noise.
