Optical systems and methods for increasing interpupillary distance of a display device

A method for increasing an effective interpupillary distance of light provided by a display screen, comprising:

• shifting, with a first beam shifter coupled with one or more display screens, first light from a first portion of the one or more display screens in a first direction;
• and
• shifting, with a second beam shifter, coupled with the one or more display screens, second light from a second portion of the one or more display screens, that does not overlap with the first portion of the one or more display screens, in a second direction that is distinct from the first direction, wherein:
• the first beam shifter and the second beam shifter are optically coupled with one or more lenses, and
• the first light provided from a first position on the one or more display screens and the second light provided from a second position, spaced apart from the first position by a first distance, on the one or more display screens have a second distance greater than the first distance after passing through the first and second beam shifters and the one or more lenses.
