Title:
LINE BEAM FORMING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/132442
Kind Code:
A1
Abstract:
A line beam forming apparatus, according to the present invention, comprises: a first laser oscillation unit for radiating a first laser beam; a second laser oscillation unit spaced apart from the first laser oscillation unit in a first axial direction, and radiating a second laser beam; and a beam focusing unit for focusing the first laser beam and the second laser beam onto an image formation surface at a predetermined position, wherein the beam focusing unit comprises a radiation-type refraction part for refracting the paths of the first laser beam and the second laser beam towards directions in which the paths move farther from each other with respect to the first axial direction.
