We present a novel technique for three-dimensional (3D) image processing of complex fields. It consists in inverting the coherent image formation by filtering the complex spectrum with a realistic 3D coherent transfer function (CTF) of a high-NA digital holographic microscope. By combining scattering theory and signal processing, the method is demonstrated to yield the reconstruction of a scattering object field. Experimental reconstructions in phase and amplitude are presented under non-design imaging conditions. The suggested technique is best suited for an implementation in high-resolution diffraction tomography based on sample or illumination rotation.
我们提出了一种用于复杂场三维(3D)图像处理的新技术。它包括通过用高数值孔径数字全息显微镜的实际三维相干传递函数(CTF)对复频谱进行滤波来反转相干图像形成。通过结合散射理论和信号处理,证明该方法能够重建散射物体场。在非设计成像条件下给出了相位和幅度的实验重建结果。所提出的技术最适合基于样品或照明旋转的高分辨率衍射层析成像中的应用。
