The applicat ion of h igh speed and high reso lution CCD is a research ho tspot in im age ac􀀁 quisit ion fie ld. A high speed image acqu isition system is introduced and designed by using a new high reso lution sc ientific leve l v isible light area CCD KA I- 0304. In the design, area CCD and signa l processor AD9840A are driven by using KSC- 100 as the tim ing and driv ing c ircuit and then the conversion o f h igh speed A /D for the CCD output o f analog signal is performed. The generated data signa l is qu ickly transferred to ex terna l SDRAM m emory. Fina lly, data w ill be sent to a computer via USB acqu isition system. Furthermo re, correlated double sampling( CDS) techno logy is adopted in the sys􀀁 tem to remove the relevant signa l no ise and the signal- to- no ise ration( SNR) is improved. The acqui􀀁 sition speed is up to 40Mbit/s. The system is featured by high integration, low no ise, h igh speed data transm ission. A fter test ing, the s
