| Abstract: | Sub-systems of nano/sub-nanosecond level high speed camera have to be synchronized precisely through programmable time delay. A scheme based on EPLD and ASIC is presented, combining digital time delay with analog time delay technique. The time delay is programmable and the resolution is up to pico-second level. The system has small volume and low cost, and can be used for parameter setting, display and control. |
