Abstract

Microlens array are defined by with microlens (10) elements that differ from each other in accordance with a probability distribution function for shaping an optical beam having a prescribed intensity profile within a desired far-field scatter pattern. The differences include random variations in sag profile corresponding to a surface shape (60) of the micro lenses, a boundary profile (46) corresponding to a boundary of the micro lenses, and a spatial distribution corresponding to the relative position of the micro lenses within the array. The sag profile variations can be used to homogenize an intensity profile of the optical beam. The boundary profile variations within an irregular spatial distribution can be used to apply the prescribed intensity profile of the optical beam within the desired scatter pattern.
