Abstract
Computer-based methods and associated computer systems are disclosed for designing free space reflective optical surfaces () for use in head-mounted displays (HMDs). The reflective optical surface () produces a virtual image of a display surface () for viewing by a user's eye (). The method includes using one or more computers to: (i) represent the display surface () by display objects (); (ii) represent the free space reflective optical surface () by surface elements (); and (iii) iteratively calculate spatial locations, normals, and radii of curvature for the surface elements () which will cause a virtual image of each display object () to be displayed to a nominal user's eye () in a desired direction of gaze of the eye ().
