Head mounted display with a roof mirror array fold

摘要

The present invention includes a head mounted display (HMD) worn by a user. The HMD includes a display projecting an image through an optical lens. The HMD also includes a one-dimensional retro reflective array receiving the image through the optical lens at a first angle with respect to the display and deflecting the image at a second angle different than the first angle with respect to the display. The one-dimensional retro reflective array reflects the image in order to project the image onto an eye of the user.

1. A head mounted display (HMD) worn by a user, the HMD including:
a display for projecting an image through an optical lens; a retro reflective array configured for one-dimensional pupil re-imaging and for receiving the image through the optical lens at a first angle with respect to the display, and deflecting the received image at a second angle different than the first angle with respect to the display to project the image onto an eye of the user; and in an X, Y, Z Cartesian coordinate system, the one-dimensional retro reflective array includes a plurality of micro-prisms, wherein each micro-prism extends uniformly in a Y-axis, and forms a right angle with an adjacent micro-prism in an X-axis, and the retro reflective array is free-of an intermediary image.
