    To realize high voltage threshold, high linear slope, simple circuit and easy debugging of ramp signal from the scan control module of streak camera, utilizing the advantages of high voltage generated by switching discharge and good linearity of constant current charging slope, we designed a simple circuit to generate high voltage ramp signal. The circuit can adjust and optimize the slope and linear rate of the linear slope signal by adjusting the resistance. The experimental results show that the linear high voltage ramp signal generated by the circuit can provide a voltage of up to 1 700 V, the nonlinear precision of the ramp is less than 3%, and the scanning time is adjustable from 200 ns to 50 μs. Compared with the traditional high voltage ramp signal circuit, the circuit is simple in structure and convenient to debug, and the ramp time can be adjusted steplessly from nanoseconds to microseconds. This can effectively improve the scanning time accuracy of the fringe camera and effectively reduce problems such as circuit crosstalk.
