Abstract
A method for calibrating includes obtaining a head-mounted display device that includes an electronic display having an array of display elements and an array of beam steerers located over an inner left portion and an inner right portion of the electronic display. The method also includes obtaining alignment information by selecting a first respective subset of the array of display elements and causing it to emit light, and determining whether the light is received by a first optical sensor in a first position or a second optical sensor in a second position, thereby determining whether the first respective subset of the array of display elements is aligned for the first or the second optical sensor. The method also includes repeating the selecting, causing, and determining operations for a second subset of the array of display elements, and storing the alignment information for calibrating images for presentation by the electronic display.
