采用ＩＣＣＤ作为探测器，用比色法检测温度场，可以快速获取温度场全面信息，达到实时检测及控制的目的。然而由于ＩＣＣＤ响应动态范围有限，测温范围受到限制，同时双波长的选择是一个困难的问题。作者提出了采用不同的曝光时间分区测量温度场的方法，以扩大检测温度范围，同时在一定温度范围内，为了得到较高、较均匀的灵敏度，通过对系统模拟计算得出了系统工作双波长的理想选择，这些理论分析与试验结果基本一致。
Using ICCD as the detector, colorimetric detection of the temperature field, you can quickly access the full information of the temperature field, to achieve real-time detection and control purposes. However, due to the limited dynamic range of ICCD response, temperature measurement range is limited, while the choice of dual wavelength is a difficult issue. The authors proposed a method to measure the temperature field by different exposure time zones, in order to expand the detection temperature range. In order to obtain higher and more uniform sensitivity in a certain temperature range, the system working double wavelength The ideal choice, these theoretical analysis and test results are basically the same.
