Abstract
Due to the development of micro-electronics in the field of multi-element optical detectors and fiber optics in the communication technology, fiber spectroradiometer now are widely used in photometry and radiometry. For most of time, the measurement environment may differ greatly from the experimental condition where calibration is made. Mistake may arise in the measurement process. An investigation of the characteristics of the fiber spectroradiometer is presented here, such as the plug and pull of the fiber optics, the bandwidth, the integration time and linearity, and short time stability. Experiments show that the bandwidth can significantly affect the accuracy of the measurement. Different from the conventional big-size scanning spectroradiometer, the measurement ability of the fiber spectroradiometer should be restricted in some application field. In measuring the spectra with multiple peaks, appropriate bandwidth spectroradiometer should be used.
