Planar high angle line generator

Abstract:

A planar line generator including a first planar surface extending in a first direction, a second planar surface facing the first planar surface, and a beam splitter in front of the second planar surface, the beam splitter configured to output, from light incident thereon, an undeflected beam, a first beam deflected to a first side of the undeflected beam along the first direction, and a second beam deflected to a second side of the undeflected beam along the first direction, wherein the second planar surface includes a line diffuser configured to receive the undeflected beam, and first and second diffusers having a design different from the line diffuser, the first and second diffusers being configured to receive the first and second beams, respectively.
