Abstract

Results of the experimental tests concerning the wavefront sensor designed for control of the laser beam transformed by the deformable multichannel bimorph mirror are presented in the paper. The sensor developed on the base of the curvature sensing method consists of the vibrating mirror of a membrane type and a multi-element detector for the beam intensity measurements. The characteristics of the sensor are analysed versus the controlled deformation introduced to the tested beam by a deformable mirror. The measurements prove that the curvature signal measured by the detector is proportional to the local distortions of the wavefront of the laser beam.
