phase-contrast method

基本解释

Surface roughness of transparency material is measured by means of light-cutting method and phase-contrast method.
运用光切法和相衬法对透明材料表面粗糙度进行测量。
We have developed a new method, X-ray phase-contrast imaging (XPCI) based on the microfocus X-ray tube, to explore microstructures of Chinese herbal medicine.
实验结果表明，这种新的成像方法可以有效地对中药材的显微结构成像。
In this paper, the synchrotron X ray source at BSRF was used to investigate the microstructure of lung, liver and kidney by means of the DEI phase contrast micro-imaging method.
本文以北京同步辐射装置产生的同步X射线束为光源，应用衍射增强成像（DEI）技术，对人和动物脏器的软组织进行相位衬度成像。

相衬法
A differential phase contrast wave-front sensing system based on an optical addressed ferroelectric liquid crystal spatial light modulator (OA-FLCSLM) is introduced, different from the traditional phase contrast method which is highly sensitive to the wave-front tilt.
针对传统相衬法对波前倾斜像差的高度敏感性,本文介绍了一种基于光寻址铁电液晶空间光调制器的差分型相衬波前传感系统。
