Scientific paper

A Hartmann device (GRIFON) was developed for simulating the operation of the wavefront sensor of an adaptive system. This device makes it possible to account for wavefront deformation of stellar radiation due to turbulent refractive-index irregularities in the Earth's atmosphere. The effectiveness of the method is confirmed by a series of Hartmann pictures obtained with the 70-cm reflector of the Kiev observatory for stars up to 3 m.
