1. An optical device comprising:
a body formed to have a concavity within which an eye box region is defined; and
one or more vertical cavity surface emitting laser (VCSEL) arrays arranged in the body of the optical device, wherein the one or more VCSEL arrays comprise a plurality of VCSEL subarrays including a first VCSEL subarray and a second VCSEL subarray, the first and second VCSEL subarrays being independently addressable; and
processing circuitry configured to control the independently addressable first and second VCSEL subarrays in a power saving mode 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, wherein
the first subregion and the second subregion are smaller than the eye box region and are smaller than a union of the first subregion and the second subregion.
