In order to solve the problems of insufficient natural lighting and blurred images taken by low-amplitude cameras in high-speed imaging,a high-brightness array pulse light source is designed.The pulse light source has the advantages of narrow pulse width,high frequency and uniform illumination.The system adopts high-power high-brightness white LED as the light source,and MCU as the core controller.LED driving circuit,precise timing control,alarm and display circuit modules are designed.The experimental results show that the pulsed light source can reach 36 000 lm and the pulse width is 1 μs,which can effectively improve the problem of high-speed target imaging blur.
