Description

Atmospheric turbulence is the major reason for blurring of the images from ground-based telescopes. In this paper, a model-based wavefront sensorless approach to remove the distortion from the images is proposed. A radial surrogate model is used to simplify the optimisation of an intensity-based objective function. To reduce the number of intensity evaluations required to build the model, the statistics of the atmosphere are extracted and explored. The number of evaluations can be further dec...
