物体的内部结构可以通过捕获透射图像来测量。然而，由于物体内部光线的强烈散射，半透明物体的记录图像往往不清晰。本文提出了一种基于并行高频照明的散射方法。我们在本文中表明，原始的高频照明方法和各种扩展技术可以统一定义为重叠和非重叠光线的分离。此外，我们通过构建并行投影/测量系统来同时进行照明和观测，表明透射光线不会相互重叠。我们已经开发了一个测量系统，由相机和投影仪与远心镜头组成，并通过提取透射光线来评估散射效应。
The inner structures of an object can be measured by capturing transmissive images. However, the recorded images of a translucent object tend to be unclear due to strong scattering of light inside the object. In this paper, we propose a descattering approach based on Parallel High-frequency Illumination. We show in this paper that the original high-frequency illumination method and the various extended techniques can be uniformly defined as a separation of overlapped and non-overlapped light rays. Also, we show that transmissive light rays do not overlap each other by constructing a parallel projection/measurement system for performing both illumination and observation. We have developed a measurement system that consists of a camera and projector with telecentric lenses and have evaluated descattering effects by extracting transmissive light rays.
