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.

Method and device for local stabilization of a radiation spot on a remote target object

A method for local stabilization of a radiation spot formed by a high energy laser beam includes receiving radiation reflected by the target object, where the radiation reflected by the target object passes through the same optical path as the high energy laser beam. An image processing is performed by analyzing and comparing the image of the illuminated target object or part of the illuminated target object to at least one image of the illuminated target object or part of the illuminated target object produced at a prior point in time. A correction signal is computed, with which an optical correction device is actuated. A filter correction signal is produced by a filter device, while a controller correction signal is produced by a fine tracking controller. Finally, the correction signal is formed from the filter correction signal and the controller correction signal.

Method, device, computer program and computer program product for tracking the path of motion of a moving object. The method includes a) providing data of at least one state variable to be determined, which influences the movement of the moving object, at a first point in time; b) initializing the probability density (p) of the at least one state variable to be determined at the first point in time; c) predicting of the probability density (p) of the at least one state variable to be determined at a next point in time after the first point in time; d) verifying of whether measurement data are available that can be used for a calculation of the probability density (p) of the at least one state variable to be determined, and d') recalculating the probability density (p) with these measurement data when such data is available; e) calculating the prediction values of the state variable(s) to be determined from the probability density (p); f) outputting the calculated prediction values to a downstream data processing device; and g) repeating the steps c) through f). The steps of initializing the probability density (p) of step b); predicting the probability density (p) of step c); recalculating the probability density (p) of step d&#x2032;); and calculating the prediction values of step e) are performed by discretizing the probability density (p) on sparse grids.
