Abstract
The result of full-screen sweeping rates of streak camera(SC) is obtained using a nonlinear-least-squares method. The uncertainty of this method is about 0.04%, far below SC’s systematic uncertainty. Full-screen result eliminates nonlinearity and space-distortion of sweeping rates, minimizes the error of SC’s measurement to about 1.5%. The robustness and time-efficiency of this method make full-screen calibration of time-domain and space-domain feasible．
