초록 ▼

A mirror-based laser processing system, e.g., for laser welding, provided with manual control of movements of a laser welding spot W on an object O being treated. The system includes a laser source (10) which generates a laser beam capable of treating the object (O), a mirror-based micromanipulator (14) which consists of a concave mirror (18) and a convex mirror (16) facing each other, and a laser beam splitter (20) which is located on the path of the laser beam reflected from the concave mirror (18). The laser beam splitter (20) has a coating which reflects the laser beam onto the object (O), but is capable of passing visible and infrared light. Movements of the laser-beam splitter are manually controlled from an external terminal, which is made in the form of a joy stick (50). The joy stick is capable of moving the laser welding spot (W) in any direction over the object\s surface in the X-Y coordinate system. Adjustment in the Z-axis direction is performed through a zoom system of the mirror-based micromanipulator (14). The infrared light which is generated by the heated area of the object passes through the laser-beam splitter which transmits visible light to the microscopic head for observation of the object and reflects the infrared light. The latter is processed by a processing unit (38) and is converted into visible thermal information presented on a display (46) in the form convenient for manual control of the position of the welding spot W.

A mirror-based laser processing system with visual tracking and controlling positions of a moving laser spot on an object, comprising: a laser source generating a laser beam capable of treating said object; a mirror-based micromanipulator which consists of a concave mirror and a convex mirror facing each other and spaced at a distance from each other, said concave mirror having a central hole for passing said laser beam, said convex mirror being located on the way of said beam passing through said concave mirror and reflecting said beam in a diverging manner onto said concave mirror, said concave mirror reflecting said beam in a converging manner; a laser beam splitter which is located on the path of said beam reflected from said concave mirror add which is inclined with respect to the direction of said reflected beam, said laser beam splitter having a coating capable of passing visible and infrared light, but reflecting said laser beam onto said object, said object being located in a focusing position of said laser beam reflected from said laser beam splitter, said laser beam splitter having means for controlling its movement with respect to said beam thus moving said laser spot over said object; an imaging beam splitter located on the side of said laser beam splitter opposite to said object and capable of transmitting a visible light but reflecting an infrared light generated by an area of said object heated by said laser spot; and an infrared tracking system for converting said infrared light into thermal information and into a visible image.
