A spectroradiometer system is described which is designed to make measurements of the spectral energy-distribution of light sources over the 0.25-2.5-micro wavelength range. A review is presented of some of the major experimental problems encountered in radiometry, in conjunction with the approach employed here to meet these problems. A single beam optical arrangement is used, with the photodetector signal being integrated over successive wavelength intervals and recorded in digital form. A digital computer then performs all subsequent data processing, including plotting of the final spectra. A brief functional description of the computer programs is presented, and the accuracy and reproducibility of the system are discussed.
本文描述了一种光谱辐射计系统，该系统旨在测量0.25 - 2.5微米波长范围内光源的光谱能量分布。结合本文为解决这些问题所采用的方法，对辐射测量中遇到的一些主要实验问题进行了综述。采用单光束光学装置，光电探测器信号在连续的波长间隔上积分，并以数字形式记录。然后由数字计算机执行所有后续的数据处理，包括绘制最终光谱。文中给出了计算机程序的简要功能描述，并讨论了该系统的准确性和可重复性。
