Abstract

In this paper, an analytic model of beam profile error evaluation for detector array method is advanced. The model based on Gaussian beam distribution considering spatial sampling frequency, the non-uniformity of detectors and the high frequency components of integral laser spot. Finally, the analytic error model of laser beam profile evaluation was obtained by derivation and calculation. The model is adapted to calculate the integral energy, the beam centroid, and beam size of Gaussian approximation beam and can be extended to monotonous distribution beam.
