中文摘要：

为了降低光谱采集系统中硬件电路的设计的复杂性,设计了一种基于线阵CCD和USB控制器的光谱采集系统。该光谱采集系统主要包括超高灵敏度线阵CCD传感器、CCD专用的A/D转换器AD80066以及CY7C68013 USB控制器;USB控制器兼备对CCD和A/D转换器的驱动以及数据传输控制的功能。实验结果表明,该光谱采集系统具有较好的信噪比（SNR）,在微型光谱仪上具有较好的应用前景。

英文摘要：

In order to reduce the hardware expenditure,a spectral data acquisition system based on linear CCD and USB controller was designed.The system included an ultra-high sensitivity linear CCD ILX511,a CCD dedicated A/D converter AD80066,and a USB controller CY7C68013.The signals for CCD driving and A/D converting,were generated by the USB controller.In the meanwhile,the spectral data transferred to computer was under the control of the USB controller.The experimental results indicate that,the system has excellent signal to noise ratio（SNR）,therefore,it has great potential applications in miniature spectrometer.
