Abstract
An optical marking system is disclosed, in which a light beam of a preset wavelength is generated by a light source. An optical system receives the light beam generated by the light source and directs the received light beam in a present direction. A pattern generator includes a pattern forming section and a non-pattern forming section. Further, a control section controls the optical system to effect a first mode, in which the light beam is directed to the pattern forming section of the pattern generator, to form a predetermined pattern and a second mode, in which the light beam is directed to the non-pattern forming section of the pattern generator. The first and second modes are effected in a preset sequence.
