Abstract: A wide-angle illuminator module including a rigid support structure having a plurality of angled faces, a flexible circuit including one or more VCSEL arrays, each VCSEL array positioned over a face among the plurality of angled faces, each VCSEL array including a plurality of integrated microlenses with one microlens positioned over each VCSEL in the VCSEL array, and a driver circuit for providing electrical pulses to each VCSEL array, wherein the plurality of VCSEL arrays address illumination zones in a combined field of illumination. The support structure may also be a heatsink. The flexible circuit may be a single flexible circuit configured to be placed over the support structure or a plurality of flexible circuits, each including one VCSEL array.
