Abstract
A lensless focusing device for receiving an unfocused laser beam and creating a desired output pattern of laser profiles. The focusing device includes a pair of wedge plates oriented at a reflective angle relative to the projection axis of the input laser beam. The focusing device generates an output pattern having a plurality of spaced laser profiles. The laser profiles include a series of fixed laser profiles and a series of adjustable laser profiles. Rotation of the focusing device about the projection axis of the input laser beam moves the adjustable laser profiles relative to the fixed laser profiles. Multiple focusing devices can be used in series with each other to generate an output pattern having a grid shape in which points on the grid are movable upon rotation of either focusing device.
