This paper is mainly relative to three parameters1 measurement , which are spectral irradiance , spectral radiance and colour temperature . the metrology of these parameters plays an important role in moder war 本文主要是进行了光谱辐照度、辐亮度及光源色温这三个参数的计量测试,这些参数的计量在现代化的战争中发挥着巨大的作用。
How the spectral irradiance and spectral radiance transfer from outside atmosphere to the instrument , further more , through optical elements of the instrument to the detector of the instrument , finally turn into output electric signals are described 通过太阳紫外光谱在大气中的传输及后向散射的计算,对太阳紫外光谱及太阳后向散射紫外光谱的变化范围有了了解。
For the spectral radiance calibration of solar ultraviolet spectrum monitor , a basc > 4 diffuser is used , and a more accurate calculation for spectral radiance response is given by a integral formula . process of download signal data from solar ultraviolet spectrum monitor on spaceship obtains measurement results of solar ultraviolet spectral irradiance and solar backscatter spectral radiance 根据太阳紫外光谱监视器的地面标定结果,对从神舟三号上下载的测量数据进行处理获得了地外太阳紫外光谱辐照度和地球大气后向散射光谱辐亮度,与国际上的测量结果对比相对误差在10 %以内。
Before 1990 , more than a dozen of overseas nations had founded the standard of spectral irradiance and spectral radiance in succession . the standard of spectral irradiance and spectral radiance in this country founded in 1980s has not met the measurement accuracy required by the research development of national defence 在90年代以前,国外陆续有十几个国家先后建立了光谱辐照度、辐亮度标准,我国国家计量院于80年代左右建立的光谱辐照度和光谱辐亮度标准已远不能满足国防科研发展对测量精度的要求。
In order to realize the measurement of several parameters and broad - band spectrum ( 250nm ~ 3000nm ) on the same standard equipment , we make use of two main light paths . one is to measure spectral radiance , the other is to measure irradiance through integral sphere , translational stage and mirror changing the light path 本标准装置涉及参数多,包括光谱辐照度、光谱辐亮度、光源色温;光谱范围宽,覆盖了紫外、可见、红外;在同一套设备上实现多参数、宽光谱以及能量强度变化为7个数量级的精确测量。
So it is very important to found a higher accuracy standard of spectral irradiance and spectral radiance . the article begins with the conclusion of measurement approaches on spectral irradiance , spectral radiance , colour temperature and blackbody temperature and introduces measurement approach , theory , system and signal measurement technique systematically 本文从总结现有高温黑体温度的测量方法、光谱辐照度的测量方法及光源色温的测量方法出发,系统地介绍了高温黑体温度、光谱辐照度、辐亮度及光源色温的测量方法,测试原理,测试系统以及相应的信号检测技术。
