An arrangement for the guidance or conductance of a beam during the treatment of a workpiece with a laser, especially during a surface treatment by the laser beam, through the intermediary of mirrors which are interposed in the path of the beam intermediate a laser source and the workpiece. At least one deflecting mirror of the mirrors is equipped with adjusting elements for implementing a locally variable topography of its mirror surface, and is actuated from a control apparatus for effectuating a deformation or distortion of the cross-sectional geometry of the beam in conformance with the measure of a specified geometry of the beam focal point on the surface of the workpiece.

A subordinate-ammunition member with a target-detecting arrangement, in which the arrangement externally of the wall of the member is oriented in parallel with the longitudinal axis of the member. The target detecting arrangement is arranged on a support which is movable relative thereto and is adapted be displaced from the interior outwardly of the wall structure of the subordinate-ammunition member.

Subordinate-ammunition member with target-detecting arrangement

An arrangement for generating a firing or triggering signal for a projectile which is conveyed in a flying body overflying a target, wherein a target identifying circuit requires a processing period for the identification of a detected target pursuant to predetermined characteristics, and in which, subsequent to a waiting period dependent upon the flying altitude, there occurs a delay or lag period between the initiation of the firing signal and the ejection or, respectively, target impact of the projectile. For the target determination, an optical sensor arrangement is directed at a first acute angle relative to the flight trajectory of the flying body; wth this angle being so calculated that at a minimum flying altitude of the flying altitude of the flying body, the flying time from the target determination up to the overflight of a certical above the target is at least equal to the sum of the processing period and the delay or lag period, and in which the sensor arrangement is set a second acute angle which is larger than the first angle after the identification of a selected target, and which takes into consideration the delay period and the flying altitude.
