With the ongoing digitalization of industry, imaging sensors are becoming increasingly important for industrial process control. In addition to direct imaging techniques such as those provided by video or infrared cameras, tomographic sensors are of interest in the process industry where harsh process conditions and opaque fluids require non-intrusive and non-optical sensing techniques. Because most tomographic sensors rely on complex and often time-multiplexed excitation and measurement schemes and require computationally intensive image reconstruction, their application in the control of highly dynamic processes is often hindered. This article provides an overview of the current state of the art in fast process tomography and its potential for use in industry.
随着工业的数字化进程不断推进，成像传感器在工业过程控制中的重要性日益凸显。除了视频或红外摄像机等直接成像技术外，在过程工业中，恶劣的工艺条件和不透明的流体需要非侵入式和非光学的传感技术，因此层析传感器也引起了人们的关注。由于大多数层析传感器依赖于复杂且通常时分复用的激励和测量方案，并需要计算密集型的图像重建，因此它们在高度动态过程的控制中的应用常常受到限制。本文概述了快速过程层析技术的现状及其在工业中的应用潜力。
