  • the measuring device 1000 has the task of measuring the relative translatory (xyz) and rotational ( ⁇ , ⁇ , ⁇ ) movements between two objects A and B. This will be explained below. Relative movements of the object B with respect to the object A in the z and y directions are detected directly by the detector 104. Movements along the x-direction, due to the non-parallelism of the beams 201 and 203, result in an offset of the signal at the detector 105 also along the opposite x-direction. A relative movement about the angle ⁇ is detected directly on the position-sensitive, flat detector 104 due to the non-circular cross-section of the beam 201. A rotation about the angle ⁇ leads to an offset of the signal at the detector 105 in the z direction.
  • a relative movement of the object B with respect to the object A by the angle ⁇ is detected at the detector 105 by an offset in the x-direction.
  • Relative translational movements in the range of less than 1/100 mm as well as rotational movements of less than 1/10 milrad can be detected with the aid of the illustrated measuring device 1000 according to the invention.
  • the measuring device 1000 on the main deck 4 of a maritime observation and defense platform 1 (whereby the main deck 4 can be displaced along the central column 3 by means of a drive device) to control the dynamic translational and rotational movements between objects A and B - for example, sensors 17, 18 and effectors 16 - on the main deck 4 to detect each other.
  • the data is transmitted by a suitable processing unit to the position sensors and actuators of the sensors 17, 18 and effectors 16 on the platform 1 and further processed there.
  • the dynamic deviations are provided for the calculation of correction values of the orientation of the effectors, i. the gun barrels of the installed cannons.

Abstract

L'invention concerne une plate-forme (1) d'observation et de défense maritime comportant une base formée d'un certain nombre de bras (2) qui s'étendent vers une colonne centrale (3) et y sont reliés de manière fixe, ainsi qu'un pont principal (4) sensiblement perpendiculaire à la colonne centrale (3) qui le traverse. Le pont principal (4) peut être déplacé le long de la colonne centrale (3) au moyen d'un dispositif d'entraînement. L'invention porte également sur un dispositif de mesure (1000) destiné à la détermination de la dynamique translationnelle et rotative relative entre deux objets (A, B) éloignés l'un de l'autre dans un espace tridimensionnel au moyen d'une source de rayonnement (100), ainsi que sur un procédé pour installer et enlever la plate-forme (1) d'observation et de défense maritime.
