Summary: | We propose a visor-based see-through head-worn light field display. The visor is a semi-reflective concave image combiner that overlays virtual imagery to the user’s visual field. The visor has a toroidal surface profile for off-axis astigmatism correction. Virtual images are created at different depths using a classical light field assembly (LFA), which comprises a microlens array and a display source. The LFA is placed at an angle above the visor, clear of the user’s line of sight. The image plane of the LFA is placed near the focal plane of the visor. Since the LFA forms virtual images farther away from the plane of the display source, the LFA itself can be brought close to the visor, allowing for a more compact display system compared to conventional head-worn displays. |
