Abstract
An addressable vertical cavity surface emitting laser (VCSEL) array may generate structured light in dot patterns. The VCSEL array includes a plurality of traces that control different groups of VCSELs, such that each group of VCSELs may be individually controlled. The VCSEL groups are arranged such that they emit a dot pattern, and by modulating which groups of VCSELs are active a density of the dot pattern may be adjusted. The VCSEL array may be part of a depth projector that projects the dot pattern into a local area. A projection assembly may replicate the dot pattern in multiple tiles.
