For the design mentioned above , the whole system has the feature of small dimension , easy operating and high accuracy . it ’ s a great improvement over the past multi - spectral pyrometers and will make the pyrometer work well under more complicated situations 以上方案的选择构成了本课题的特色,使得整个设备在较为精确地测量目标真温和发射率的同时,也具备了体积小、操作方便灵活、可靠性高等优点。
( 2 ) a continuous measurement method based on brightness temperature is proposed by processing the measured data of the multiwavelength pyrometer at two different times , the true temperatures and spectral emissivities at two different times can be calculated simultaneously . the experimental results show that this method improves the measurement precision of true temperature and spectral emissivity ( 2 )提出了基于亮度温度模型的连续测量法,通过处理多波长温度计两个不同温度处的测量数据,可以同时求得两个不同温度处被测目标的真温及光谱发射率,试验表明:该方法可以提高计算精度。
