Device capable of determining the direction of a target in a defined frame of reference

Abstract

The invention concerns the field of focusing and aiming instruments and more particularly a device for determining the direction of a target in a predetermined index mark comprising a focusing element, a resetting device for resetting the focusing element and a device for processing signals derived from the focusing element, the processing device determining values representing the direction between the focusing element and the target and transmitting the values to a display or an external system. The device is characterized in that the focusing element has a focusing member of three gyrometers arranged along three axes substantially perpendicular to one another and a controller that controls the transmission of the values representing the direction between the focusing element and the target to the display or to the external system.
