Abstract
The invention relates to a device for measuring relative position error between a laser beam and a target. The target is provided with a circular orifice occupying a reference position relative to said target. The device has means for focusing the laser beam in the plane of said target, means for taking an image of said circular hole and of the beam focused in the plane of said target, and means for calculating the components of the segment joining said point of impact and the center of said hole.
