光学诊断 meaning in English

optical diagnostics

The intensity of up to four spectral lines can be simultaneously measured . the flame temperature distribution in the axial direction of solid propellants is measured using the spectroscopic diagnostic system
利用建立的光学诊断系统对sq - 2推进剂以及丁羟推进剂的燃烧火焰的轴线上的温度分布进行了研究。
A quick spectroscopic diagnostic system for the flame temperature is set up in this paper . it consists of an optic imaging system , a scanning system , a dispersive system , a photoelectricity conversion cell , operational amplifiers , a computer - based data collection system and a data processing . the temperature profile varying with the time can be quickly measured by this system
目前光学诊断由于其相应快、精度高,属于非接触式测量手段,在研究中得到越来越多的应用,这里要介绍的就是本文中建立的一套光学诊断系统,它由高压燃烧室、旋镜扫描仪、旋镜控制器、小型光栅摄谱仪、光电转换装置,微弱信号放大器以及数据采集系统组成。
