Paper Abstract

In between the star-oriented tomographic measurement of atmospheric layers, and the pure layer-oriented one, there is a simple third option, which measures the turbulence in the layers' images proper by a Hartmann-Shack type sensor. The wide field is achieved by looking at multiple stars in each lenslet. The method is simple to use, but requires a fast, sensitive camera with many pixels for the lenslets' wide fields. Most of the empty pixels (without stellar images) are skipped during read-out.
