METHOD FOR AUTOMATED ADJUSTMENT OF OPTICAL SYSTEM Russian patent published in 2015 - IPC G02B27/62 B23K26/04 

FIELD: physics.

SUBSTANCE: method includes obtaining images of an adjustment laser beam and markers of control elements of the optical system, the centre of which is determined from a pair markers located on both sides of the centre, equidistant therefrom. The method also includes performing random inclination of the control optical elements, controlling change in position of images of the markers and the adjustment laser beam by calculating deviation of the centre of mass of said images from the optical axis of the system, calculating control signals which are transmitted to drives of actuating mechanisms of the control optical elements. The control signals are calculated using a stochastic parallel gradient (SPG) algorithm, the target function of which depends on deviation of the centre of mass of images from the optical axis of the system. A parameter which controls the rate of convergence of the SPG algorithm is defined by the current value of deviation of the centre of mass of the image from the position of the optical axis.

EFFECT: easier and more reliable automated adjustment of the optical system.
