| Zusammenfassung | A solution to the problem of quantitative wavefront reconstruction from shearing interferograms will be presented. The evaluation is based on Fourier filtering with a transfer function specifically determined for this purpose. The influence of the edge of the pupil is taken into account by using a novel window function. This technique does not require any a priori information about the shape of the wavefront. It reconstructs the wavefront inside the whole aperture and gives accurate results with a high lateral resolution for relatively large shears. |
