A versatile, mobile, automatic recording spectroradiometer of high precision and accuracy has been developed. The instrument is a single-beam device with an alternate reference beam intended primarily for measurements of spectral irradiance. However, it is equally useful for measurement of spectral radiance, transmittance, or reflectance. The system is programmed for automatic operation. The output is in the form of an automatic digital recording of both measurements and control data. Instrument operation integrates the following characteristics: wavelength-by-wavelength operation in intervals of 0.1 nm to 50 nm; time-integrated measurements of spectral flux; internal calibration reference source; and monitored signals for wavelength position, test source total output, and photodetector dark current. The system's operating characteristics and specifications have been determined and are set forth here. Performance for three types of sources and correction of measurements to zero-bandpass equivalence is demonstrated.
已经研制出一种多功能、可移动、高精度和高准确度的自动记录光谱辐射计。该仪器是一种单光束装置，带有交替参考光束，主要用于测量光谱辐照度。然而，它同样适用于测量光谱辐射率、透射率或反射率。该系统已编程实现自动操作。输出形式为测量和控制数据的自动数字记录。仪器操作具有以下特点：波长间隔为0.1纳米至50纳米的逐波长操作；光谱通量的时间积分测量；内部校准参考源；以及波长位置、测试源总输出和光电探测器暗电流的监测信号。已确定该系统的操作特性和规格并在此列出。展示了三种类型光源的性能以及将测量值校正为零带通等效值的情况。
