Conventional control circuits are composed of discrete components and Medium Scale Integration (MSI) and Small Scale Integration (SSI)  which have bad reliability and poor ability of anti-interference. The idea of using the Complex Programmable Logic Device (CPLD) to realize the monostable trigger circuit is introduced. On the basis of analyzing the performance requirement to the synchronization control of the laser range gated imaging system  a new synchronization control circuit based on CPLD is presented. The circuit based on CPLD is very compact and flexible and has high reliability and strong ability of anti-interference. The synchronization control circuit based on CPLD can provide a wide selection of gate widths  pulse widths and delays. The synchronization control circuit is successfully used in our experiment and the expected result is obtained.
