Design of Spectral Acquisition System Based on the Linear Array CCD ILX554B

The linear array CCD spectral acquisition system for a Photoelectric Direct Reading Spectrometer is presented. The spectral acquisition circuit, data processing and shortage circuit are designed. Taking microcontroller MSP430 as a control chip, Using PWM signals generated by MSP430 timer, the correct timing of CCD clock pulse, ADC clock and FIFO write enable signal was established. The experiment shows that the synchronization of spectral acquisition, data conversion and shortage was achieved, and the spectral acquisition system is feasible and reliability.
