10. Method for measuring the position of at least one moving object in a three-dimensional grid using a device for measuring the position of said at least one object comprising:
-
at least one optical head comprising an independent laser sources array outputting collimated laser beams, arranged about a central photodetector with a single sensitive cell, at least one movable base with two rotational degrees of freedom whereto said array is secured, characterised in that it comprises; a static and local scanning step with laser sources switching for tracking the object, an overall tracking step of said at least one object performed by consulting both axes of a movable base of said array to continuously adjust the angles of said movable base in order to align the centre of the photodetector with the centre of the object. - View Dependent Claims (11, 12, 13, 14)
