Abstract: Methods, devices and systems are described for selectively illuminating different zones of a field of view by a multi-zone illumination device. In one aspect, a multi-zone illuminator may include a plurality of vertical cavity surface emitting lasers (VCSELs), and a plurality of micro-optical devices aligned with apertures of individual or groups of VCSELs, which are configured to be individually activated to provide adjustable illumination to different zones of a field of view of an image sensor. In another aspect, a method of selective illumination may include receiving information specifying a field of view of a camera, and controlling at least two sub arrays or individual illuminators of an illuminating array to output light at independently adjustable illumination powers, wherein each of the at least two sub arrays are independently configurable to illuminate at least one of a plurality of separate zones corresponding to the field of view of the camera.

Abstract: A VCSEL array device formed of an array of raised VCSELs on an electrical contact and raised inactive regions connected to the electrical contact. The VCSELs can be physically and/or electrically organized to improve power or speed, or in phase and in parallel. The VCSELs and inactive regions are positioned between the electrical contact and an electrical waveguide. The VCSELs may be separated into subarrays and each VCSEL may be covered with an integrated or bonded microlens for directing beams of light without external lenses. The VCSELs may also be electrically selected to form two or more groups, with beams of light from each group have unique divergences, unique power or unique optical power, and each beam of light in a group forming a spot at a point on a line, on the same optical axis, or as part of a pattern.
