在过去的十年中，使用ICCD相机作为表征非平衡等离子体的手段一直在稳步增加。由于其高灵敏度和高速可选性，ICCD相机可以进行时间分辨的解剖研究，并且当与滤光片、单色器、光谱仪或激光系统一起使用时，可以对非平衡等离子体放电的物理和化学性质进行时间分辨的研究。本文旨在介绍ICCD技术及其作为等离子体诊断技术的使用，讨论与使用ICCD相关的典型实验问题，并为读者提供如何解决这些问题的实际示例和建议。特别地，讨论了ICCD相机与驱动等离子体放电的电压脉冲同步以及研究小体积放电的问题，主要集中在非平衡大气压等离子体射流的情况下。最后，提出并讨论了一种实现等离子体放电发射绝对校准的可能方法。这里提供了广泛的数据（大部分未发表）来说明这些观点。
Over the past decade the use of ICCD cameras as a means for characterizing non-equilibrium plasmas has been steadily increasing. Due to their high sensitivity and high speed gateability, ICCD cameras enable time-resolved studies of the anatomy and, when adopted in conjunction with filters, monochromators, spectrometers or laser systems, time-resolved investigation of physical and chemical properties of non-equilibrium plasma discharges. This paper is meant as an introduction to ICCD technology and its use as a plasma diagnostic technique, discussing the experimental problems typically associated with its use and providing the readers with practical examples and suggestions on how to address them. In particular, the issues of ICCD camera synchronization with the voltage pulse driving the plasma discharge and of investigating small volume discharges are addressed, focusing mainly on the case of non-equilibrium atmospheric pressure plasma jets. Finally, a possible way to achieve absolute calibration of plasma discharge emission is presented and discussed. A wide range of data, mostly unpublished, is provided here to illustrate the points.
