论文摘要
任何实用的成像系统,无论是反射,折射还是基于衍射,都基本上都是频带限制的,因此必将受到通风模式噪声的影响。 PassBand的暂停最常用作摆脱这些不必要的伪影的首选方法。但这是由于较高的频率逐渐变细而失去分辨率的代价。在这里,我们提出并演示了一种新型技术,用于根据其阶段区分通风的裂片。因此,我们可以在不妥协成像系统的情况下消除主要的嘈杂裂片。
Any practical imaging system, be it reflection, refraction, or diffraction-based, is basically band limited and therefore is bound to be affected by airy pattern noise. Apodization of the passband is most often applied as a preferred method to get rid of these unwanted artifacts. But it comes at a cost of losing resolution as higher frequencies are tapered in apodization. Here, we propose and demonstrate a novel technique for discriminating the airy lobes based on their phase. We could thus eliminate the dominant noisy lobes without compromising with the resolution of the imaging system.
