由于等离子体物理、空间物理、光化学以及激光器的发展,需要在紫外和真空紫外光谱区进行精确的辐射测量。和其他光谱区一样,根据不同的情况,可以使用标准光源或标准探测器。紫外和真空紫外探测器标准,可以用绝对温差电偶和电离室技术,并已发展了相应的传递探测器。关于发射标准的建立,已经使用两种方法——同步辐射和壁稳弧。同步辐射的 Due to plasma physics, space physics, photochemistry, and laser development, accurate radiometric measurements in the UV and VUV spectral regions are required. As with other spectral regions, standard light sources or standard detectors can be used depending on the situation. The UV and VUV detector standards, which can be used with absolute thermocouple and ionization chamber techniques, have developed corresponding transfer probes. With regard to the establishment of launch criteria, two approaches have been used - synchrotron radiation and wall stabilization. Synchrotron radiation
