In order to make the streak camera more effective in some special circumstances, an intelligent UV picoseconds streak camera was designed, which was based on embedded computer PC -104,microcontroller 8051, and organic light emitting display (OLED). The streak camera control system was composed of digital control multiplied sweep circuit, working condition set circuit, strobe circuit for the image intensifier and adjustable high voltage power supply circuit. These circuits were implemented by embedded PC-104 via many interfaces, such as input/output (I/O) interface, analogue to digital (A/D)and digital to analogue (D/A) controller. The camera system was superior to conventional streak cameras in automatically adjusting the parameters, remote operating and system diagnostics. The experimental results show that the control system is stable, time resolution is up to 100 ps, and sweep nonlinearity is less than 5%.
