METHOD AND APPARATUS FOR THREE-DIMENSIONAL TARGETING USING GALVANO MOTOR SCANNING APPARATUS

This invention relates to a method of three-dimensional targeting, by galvano motor scanning head means using a combination of pre-objective and post-objective scanning techniques whereby a collimated input to collimated output beamexpander (2, 3) is used to size a beam or laser beam input into said...

Zusammenfassung:	This invention relates to a method of three-dimensional targeting, by galvano motor scanning head means using a combination of pre-objective and post-objective scanning techniques whereby a collimated input to collimated output beamexpander (2, 3) is used to size a beam or laser beam input into said galvano motor scanning head and a flat-field or f-Theta or telecentric lens (6) or lenses are used to focus said beam or laser beam at a target plane and where altering the separation of the elements (2, 3) within said beamexpander will alter the beam or laser beam from a collimated to a converging or diverging output into said galvano motor scanning head to alter the focal distance to said target plane.
