The full micrograph is subdivided into, say, 2048i2048 pixel patches for which the defocus and astigmatism parameters are determined. The axis of the astigmatism is turned by 908 like found in the experiment. The beam profile is elliptical due to the strong value of astigmatism pre-corrected (4l). The ray tracing analysis yields a set of characteristics of interest to optical designers, including distortion, astigmatism, and chromatic aberration. For instance, two boys had mild or low hyperopia, one had myopia, and one had a relatively important astigmatism. The precompensation approach showed that we were able to introduce 3l of astigmatism with no arm for the system. Astigmatism is normally seen as a - not always avoidable - flaw in the data. These doubts were based upon a fundamental optical phenomenon called astigmatism, which can be described as follows. But such strong astigmatism does not dramatically decrease the spatial resolution of the image and still in both directions the spatial resolution is very high. Based on these measurements, a ' map ' is generated covering the full micrograph that characterises the defocus and astigmatism values over the image. Therefore, we introduced a deep deformation of the mirror, pre-correcting a 4l astigmatism aberration, and studied the phase residues at the final distance (36 m) as before. The images 3a-3c show the far field spot obtained scanning through focus and image 3d shows the improved far field obtained after correction for astigmatism. This demonstrates a lack of significant astigmatism. He was asked whether it was not the case when men get wrong glasses that the astigmatism becomes very much worse.
