Abstract
A driving optical system is used to observe a disturbance of a wavefront of reference light received from a target and generate a wavefront in a conjugate relationship with the wavefront. A plurality of control signals are generated on a basis of a plurality of Zernike coefficients calculated as a Zernike polynomial which approximates the wavefront disturbance in order to respectively drive a plurality of deformable mirrors included in the driving optical system. An adaptive optical system is provided which can optically compensate a wavefront disturbance derived from an atmospheric fluctuation even in a case of radiating laser light to a target moving at a high speed.
