Patent number: 9466941Abstract: A patterned retarder is described that may be used with a laser source array to obtain a combined beam suitable for laser image projection (e.g., three-dimensional laser image projection using orthogonal polarization states and/or orthogonal color spaces). An effect of the retarder on a polarization state of an incident beam may be dependent on the location of the retarder upon which the beam is incident. In one example, a method of producing a laser beam from a plurality of component laser beams includes directing the plurality of component laser beams onto corresponding regions of such a patterned retarder having a plurality of pattern elements.Type: GrantFiled: March 15, 2013Date of Patent: October 11, 2016Inventors: Peter Janssens, Koenraad Vermeirsch
