The possibilities of wavefront generation by amplitude holograms are theoretically and experimentally investigated. Holograms could be generated in any PC using a MATLAB program developed by the author. The wavefronts of the generated holograms are obtained experimentally and confirmed by theoretical calculations both qualitatively and quantitatively. The errors of wavefront restoration are obtained on the example of the first 12 Zernike aberrations. The effect of the pixel size and pixelate noise on hartmanogramms of the generated wavefront and restored wavefronts are experimentally investigated.
