Acoustic-optical device for correction of a laser beam direction in the technology of incremental production from metal alloys, using a laser beam, and method for correction of a laser beam direction in the technology of incremental production from metal alloys, using a laser beam

摘要

the subject invention is a device akustyczno - optical correction direction of laser beam in incremental technology manufacturing metal alloy using laser beam (2),the device has akustyczno - optical medium (3), using, inter alia.the phenomenon of diffraction and / or laser beam refraction on acoustic waves (4) to control the light incident on the medium akustyczno - optical (3) laser beam (2).the device further has a digital to analogue converter (10) connected to akustyczno - optical medium (3) in such a waythat generated by a digital to analogue converter (10) electrical impulses are in medium akustyczno - optical (3) acoustic wave (4),while directed to the medium (3) electrical signals reflect the digital layer 3d model produced an objectand each single layer precisely odwzorowywana is by the length of the acoustic wave according to the 3d model.the subject of the invention is also a correction laser beam direction in incremental technology manufacturing metal alloy using laser beam.
