Abstract
Optical systems and methods for operation thereof are disclosed. A delimited zone is defined as a function of distance from the optical system based on a VAC limit, the delimited zone having at least one distance threshold. A virtual distance of a virtual depth plane from the optical system at which a virtual object is to be displayed is determined. It is determined whether the virtual distance is outside the delimited zone by comparing the virtual distance to the at least one distance threshold. A collimated pixel beam associated with the virtual object is generated by a projector of the optical system. The collimated pixel beam is modified to generate a modified pixel beam if the virtual distance is outside the delimited zone. Modifying the collimated pixel beam includes converging the collimated pixel beam and/or reducing a diameter of the collimated pixel beam.
