Method and Device for Local Stabilization of a Radiation Spot on a Remote Target Object

摘要

A method for local stabilization of a radiation spot on a remote target object, where the radiation spot is formed by a high energy laser beam that is aimed at the target object by a high energy radiation emitter, the includes illuminating the target object is illuminated by an illumination beam that is aimed at the target object by an illumination device. The method also includes receiving, by an image acquisition device, radiation reflected by the target object that is illuminated by the illumination beam, where the radiation reflected by the target object to the image acquisition device passes through the same optical path as the high energy laser beam. An image processing is performed by analyzing and comparing an image of the illuminated target object or part of the illuminated target object acquired by the image acquisition device to at least one image of the illuminated target object or part of the illuminated target object produced at a prior point in time or to an image stored in an object database. And a correction signal is determined, based on the comparison, with which an optical correction device arranged in the optical path passed through by both the high energy laser beam and the reflected radiation is actuated.

1. A method for local stabilization of a radiation spot on a remote target object, wherein the radiation spot is formed by a high energy laser beam that is aimed at the target object by a high energy radiation emitter, the method comprising:
illuminating the target object is illuminated by an illumination beam that is aimed at the target object by an illumination device; receiving, by an image acquisition device, radiation reflected by the target object that is illuminated by the illumination beam, wherein the radiation reflected by the target object to the image acquisition device passes through the same optical path as the high energy laser beam; performing an image processing by analyzing and comparing an image of the illuminated target object or part of the illuminated target object acquired by the image acquisition device to at least one image of the illuminated target object or part of the illuminated target object produced at a prior point in time or to an image stored in an object database; determining a correction signal, based on said comparing, with which an optical correction device arranged in the optical path passed through by both the high energy laser beam and the reflected radiation is actuated.
