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.

Wide-angle illuminator module

Systems, methods, and devices disclosed herein relate to optical assemblies for spatial multiplexing, multi-zone illumination, and optical assemblies. In embodiments, light source arrays are aligned with one or more micro-lens assemblies to generate a specific field of illumination. In embodiments, surface-emitting light sources may be light-emitting diodes and/or surface-emitting lasers. The micro-lens array may be aligned with the light source arrays, on-axis or off-axis to a principal axis of corresponding lenses such that the light sources may be expanded to a desired divergence and field of illumination. In embodiments, multiple light sources may be combined to increase power output for a specific area of the field of illumination, and light sources may be driven independently depending on intended illumination.
