Abstract
The wavefront sensor of Hartmann type consists of two parts: the optical and algorithmic. The parameters of the optical part of the sensor may vary. Since the time of “frozen” turbulence due to the Fried’s length and to the cross wind transport turbulent distortion speed, the measurement Shack-Hartmann sensor depend on the intensity of turbulent distortions. In this paper are presented the results of the analysis of the measurements of the sensor according to the size of lens array and to the intensity of turbulent distortions. The analysis is performed on basis of a numerical model of the Shack-Hartmann wavefront sensor and on Kolmogorov’s turbulence model.
