Patent ID: 7714250

Claim:
A system for machining objects using a laser beam, comprising: an object support tray to convey an object with prepositioning on a reference surface; a laser source; a galvanometric head comprising: a wide field camera with a focusing lens, with a first filter located at an output from the wide field camera, a narrow field camera with a focusing lens, with a second filter located at an output from the narrow field camera, a guide mirror moveable between a first position and a second position, the first position blocking an output of the laser and reflecting light to the narrow field camera or the wide field camera, the second position not blocking the output of the laser source, galvanometric deflection mirrors, and a lens that displays at least one object located on the tray, wherein the wide field camera, the narrow field camera, and the laser source are disposed to use partly a same optical path that includes the galvanometric deflection mirrors and the lens that displays at least one object located on the tray; a computer on which a shape recognition software is installed for checking operation of the wide field camera, the narrow field camera, the laser source, and movement control means for the galvanometric head, wherein the computer is configured to determine first location coordinates of an object in an image of the wide field camera in a first coordinate system, to determine second location coordinates of the object in an image from the narrow field camera in a second coordinate system, and to determine a relationship between the first location coordinates and the second location coordinates.
