we demonstrate a multi-parameter calibration method of the streak camera and the framing camera with the help of beam division delay and attenuation devices in an integrated optical system based on sub-picosecond short-pulse uv laser. in the designed optical scheme, the four operating modes employed the optical delay, beam division delay and attenuation, and etalon modules can be switched to synchronize the uv laser pulse with the trigger signal of diagnosis instruments, calibrate the temporal resolution and dynamic range of framing cameras, and correct the sweep speed of streak cameras, respectively. the results show that the delay time error of +/-0.1 ns in the optical delay module, the uniform distribution of sub-beams with the delay time precision of +/-0.03 ps and isocon descending energy in the beam division delay and attenuation modules, and pulse broadening of similar to 22% in the whole system are achieved. in the meantime, the experiment results display the sweep speed of 1.2 ps/pixel in a streak camera and the dynamic range of 131 in a framing camera. the proposed folding optical system with high-precision, low-loss and multi-function can be extensively applied in the temporal calibration of diagnosis instruments such as streak cameras and framing cameras.
