Abstract

A phase-contrast volume holographic imaging system for three-dimensional contrast enhancement is presented. The system utilizes a spatial filter placed on a conjugate plane to the volume holographic pupil to simultaneously enhance weak phase information at different depths within an object. The proposed system was validated with experimental image data obtained in mouse colon samples and quantitative measurements of modulation transfer function as well.

摘要

提出了一种用于三维对比增强的相衬体全息成像系统。该系统利用放置在与体积全息光瞳共轭平面上的空间滤波器，同时增强物体内部不同深度处的弱相位信息。该系统使用在小鼠结肠样本中获得的实验图像数据进行了验证，并进行了调制传递函数的定量测量。
