| titleOfInvention | Improvements in or relating to augmented reality display units and augmented reality headsets including the same |
| abstract | An augmented reality display unit for an augmented reality headset or the like, comprising: a front and rear variable power compressed liquid lens assemblies (220, 230) optically aligned with each other on an optical axis (O), a transparent waveguide display (240) interposed between the front and rear liquid lens assemblies (220, 230), and a selectively operable adjustment mechanism for adjusting the power of the front and rear compressed liquid lens assemblies (220, 230); wherein each of the front and rear compression liquid lens assemblies (220, 230) comprises a liquid filled enclosure (225, 235), the liquid filled enclosure (225, 235) having a first wall formed by an expandable elastomeric membrane (226, 236), a second substantially rigid wall (223, 233) formed by or supported on an inner surface of a transparent plate or rigid lens having a fixed optical power, and a collapsible sidewall (227, 237), the expandable elastomeric membrane (226, 236) being held under tension around its edges by an outer peripheral support ring, the membrane forming an optical surface having a variable optical power, the adjustment mechanism being arranged to move the support ring parallel to the optical axis (O) towards or away from the second wall for increasing or decreasing the liquid (228, 235) within the enclosure, 238) To expand or contract, respectively, the membrane parallel to the optical axis for changing the optical power of the optical surface of the membrane (226, 236); wherein the second wall (223) of the front compressed liquid lens (220) is formed of or supported on a transparent or rigid lens (222), the transparent or rigid lens (222) being inclined at a first angle with respect to the optical axis to introduce a first degree of prism into light passing therethrough, the second wall (233) of the rear compressed liquid lens being formed of or supported on a transparent or rigid lens (232), the transparent or rigid lens (232) being inclined at a second angle with respect to the optical axis to introduce a second degree of prism into light passing therethrough, wherein the first and second degrees of prism are substantially equal and opposite to each other. |
