The design of the Range-gated synchronization control circuit is one of the key techniques in the scannerless lidar imaging system,which is directly related with the imaging of target.On the basis of the performance requirement to the synchronization control circuit of the imaging system,the paper realized the synchronization control of pulse lasers and gated ICCD camera based on CPLD.A nanoseconds range-gated synchronization control circuit is designed based on VHDL language.The circuit can improve its imaging quality and its action distance by conveniently adjusting pulse width and delayed time.
