Abstract:
An enhanced panoramic HMD that and related method of displaying an image employs an improved configuration of optical elements to achieve wider field of view as compared to conventional configurations. An HMD type display device includes a first optical element, coupled to the display device, configured to direct a central set of rays and a peripheral set of rays; a second optical element, coupled to the first optical element, configured to direct the central set of rays at a central image point; and a third optical component configured to direct the peripheral set of rays to a peripheral image point. The first optical element may include a microlens array wherein the microlens array comprises a plurality of individual microlenses; the second optical component may include a collimating lens; and the third optical component may include a mirror configured to reflect the peripheral set of rays to the peripheral image point.
