Abstract

In adaptive optics,Hartmann-shack wavefront sensor and image acquired from camera has been widely used to detect incident wavefront and the application of laser wavefront correction. A numerical simulation method of generating high resolution virtual camera image, which is based on Fourier optics and realized by FFT algorithm, is mentioned in this paper. In the condition of incident laser beam wavefront with only tilt phase aberration, calculating deviation of centroid offset between the result from virtual camera image and theoretical value, is compared to verify the accuracy of this numerical simulation method and virtual Hartmann-shack image generation model.
