Abstract: An optical device is provided, including a body formed to have a concavity within which an eye box region is defined; and a plurality of addressable vertical cavity surface emitting laser (VCSEL) arrays arranged in the body of the optical device. The one or more VCSEL arrays comprise a plurality of VCSEL subarrays including independently addressable first and second VCSEL subarrays, which are controlled so as to power the first VCSEL subarray and not the second VCSEL subarray to illuminate only a first subregion of the eye box region, or to power the second VCSEL subarray and not the first VCSEL subarray to only illuminate a second subregion of the eye box region.
