The collimated laser light is incident onto an array (1 x N or M x N) of Beam Splitter DOE to split the input beam into N beams. The N output beams make some separation angle with the Beam Splitter DOE and there exists the desired zero-order beam for an odd number of beams (N). The focusing lenses are often used to achieve the output at the desired working distance.
