Zusammenfassung:	A miniature structured light illuminator is provided. The miniature structured light illuminator uses a semiconductor surface emitting array including VCSEL or RC-LED array and an array of microlens elements to generate a wide range of structured light illumination patterns. The emission beam from a surface emitter array may be selectively directed, steered, focused or expanded, by applying a lateral displacement of the microlens array, such that centers of the emission beam and microlens array are misaligned. Emitted beams may be directed through small optical components to project the structured light pattern to a distant plane. The surface emitting arrays may be configured in addressable form to be activated separately for continuous or pulsed operation with very fast pulses having
