Abstract:

Choice of the parameters of the lens raster in a Shack–Hartmann wavefront sensor with the minimal residual error in the wavefront reconstruction is one of the solutions to the problem of the sensor measurement accuracy. This paper presents the results of numerical experiments on estimating the accuracy of reconstruction of the wavefront distorted by atmospheric turbulence taking into account the transfer functions between the telescope and the sensor and between the raster and the photosensitive matrix of the receiving device.

Keywords:

Shack–Hartmann wavefront sensor, turbulent distortions of the light field, algorithm for calculating lenslet parameters
