Semi-reflective visor-based compact head-worn light field display

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.

Automated summary

We present a visor-based see-through head-worn light field display that utilizes a semi-reflective concave image combiner to overlay virtual imagery onto the user's visual field. The visor incorporates a toroidal surface profile for correcting off-axis astigmatism. Virtual images are generated at different depths using a conventional light field assembly (LFA) comprising a microlens array and a display source. The LFA is positioned above the visor at an angle and is located near the focal plane of the visor. This design allows for a more compact display system compared to traditional head-worn displays.
