Abstract: 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.
