近二十年来，化学物种层析成像(CST)被广泛应用于气体流场的多维测量。CST为多种热化学参数的时空分辨成像提供了独特的能力。它从根本上说是坚固耐用的，高度敏感，并适用于工业过程和大型燃烧系统。用于实施CST测量的仪器方法对于确定CST可能成像的物理和化学变量至关重要。在这方面，我们有三个主要目标：(A)从光学和电子学的角度讨论科技委仪器的最新进展；(B)突出系统在满足对时间和空间分辨率的日益增长的要求方面所面临的持续挑战；以及(C)审议下一代科技委仪器的潜在发展。
Chemical species tomography (CST) has been deployed in a wide range of applications in the last two decades for multi-dimensional measurement of gaseous flow fields. CST offers unique capability for spatiotemporally resolved imaging of multiple thermochemical parameters. It is fundamentally robust, highly sensitive, and adaptable to industrial processes and large-scale combustion systems. The instrumentation methods used to implement CST measurements are critical in determining the physical and chemical variables that may be imaged by CST. In this perspective, we have three main objectives:(a) discuss recent advances in CST instruments from the viewpoint of optics and electronics;(b) highlight the on-going challenges for systems to address the ever-increasing requirements on temporal and spatial resolutions; and (c) consider potential developments for next-generation CST instrumentation.
