摘要: The method utilizes a multi-faceted holographic optical element, the various individual diffraction gratings of each facet collectively functioning to effect desired wavefront transformation. In this way, laser beam can be transformed into specific pattern, permitting unusually shaped objects efficiently illuminated with light.
