Addressable vertical cavity surface emitting laser array for generating structured light patterns

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...

Zusammenfassung:	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.
