摘要 海洋光学浮标近表层光谱辐射计使用了8台PC2000-PC104型光纤光谱仪对海水4个层面8个通道进行光谱测量.本文介绍了光谱辐射计系统的组成、通信协议及PC2000-PC104型光纤光谱仪的光谱采集原理.特别是对于不正常的光谱采集结果进行了分析,提出了中断触发的4种可能情况,并对于光谱采集的异常现象作了解释.编写了完全封装的光谱仪数据采集类,解决了该问题. Eight Ocean Optics PC2000-PC104 miniature fiber optic spectrometers are used in the ocean radiometric system to measure downwelling spectral irradiances and upwelling spectral radiances at four depths. In this paper the configuration of that system is introduced as well as the method of acquiring multi-channel data. Especially, the abnormal spectral data acquired from A/D card is analyzed. And it is found that there are four possibilities when the interrupt service routine (ISR) that read data from FIFO in the A/D card is running. It is the reason that leads to above abnormity. Finally, based on the OOP, the CADCard class that provides all the base functionality of the PC2000-PC104 spectrometer is built to implement multi-channel data acquisition readily using C++.
