Laserbeam Characterization

Extremely curved wave-fronts

Measuremant of a Extremely Curved Laser Beam

In this example the measurement of an extremely curved wave-front with SHSLab HR is shown. The spots of each microlens are situated far outside of their respective subaperture. The powerful spot assignment algorithm which has been developed by OPTOCRAFT ensures an unambiguos assignment of the spots. Therefore, Shack-Hartmann-sensors of OPTOCRAFT provide an extreme dynamic range of measurable wavefronts.
