Abstract
In order to ensure the linear array CCD normally and stably working in the spectral measurement, the data acquisition and storage circuit is presented. On the basis of analyzing the ILX511 driving timing, the circuit of data acquisition, processing, and storage based on CCD was designed. The CPLD was used to establish the correct sequence for the CCD clock pulse, AD converter clock, and FIFO writing signal, so the data acquisition, converter, and storage synchronously are achieved. The experiments show that the designed circuit is feasible.
