Abstract
A device includes an illumination device for emitting an illumination beam. The illumination device includes an emitter array including multiple light emitters; and a micro-lens array (MLA) including multiple micro-lenses. The MLA is positioned to receive light emitted from the emitter array. Light from the MLA forms the illumination beam. A first region of the MLA is offset from the emitter array by a first offset amount, and a second region of the MLA is offset from the emitter array by a second offset amount different than the first offset amount.
