Abstract
A laser irradiation apparatus includes a laser source configured to emit a laser beam to an object that is being conveyed to allow the object to be irradiated with the laser beam; a rotation detector configured to detect rotation of the object to obtain information on the rotation of the object; and circuitry configured to control laser irradiation onto the object based on the information on the rotation of the object.
Claims12
A laser irradiation apparatus comprising:
- a laser device configured to emit a laser beam to an object conveyed in a conveyance direction;
- a rotation detector configured to detect rotation of the object to obtain rotation information of the object;
- and
- circuitry configured to control the laser device to irradiate the object with the laser beam based on the rotation information of the object detected by the rotation detector.
