摘要： The present invention is a head-mounted virtual display apparatus based on a non-cross-cavity optical configuration, in which a near-eye light deflecting element (LDE) is located in the peripheral field of view. Positioning of the near-eye LDE in the peripheral field of view provides the user with simultaneous access to an inset magnified image of a miniature display and an unobstructed forward field of view of at least 35 degrees. Active and passive alignment means, including articulating connections and image warping electronics, allows for correction of geometric distortion arising from folding of the optical train, and orthogonal alignment of the virtual image plane with the optical axis between the user's eye and the virtual image plane.

摘要： The present invention is a head-mounted virtual display apparatus based on a cross-cavity optical configuration, in which a near-eye light deflecting element (LDE) is located in the peripheral field of view. Positioning of the near-eye LDE in the peripheral field of view provides the user simultaneously with “look toward” access to an inset magnified image of a miniature display and an unobstructed forward field of view of at least 35 degrees. Active and passive alignment means, including articulating connections and image warping electronics, allow correction of geometric distortion arising from folding of the optical train and/or embodiments based on off-axis optical configurations.

摘要翻译： 本发明是一种基于跨腔光学配置的头戴式虚拟显示装置，其中近眼光偏转元件（LDE）位于外围视场中。 近视眼LDE在周边视野中的定位使得用户同时“看向”访问微型显示器的插入放大图像和至少35度的无障碍前视场。 主动和被动对准装置，包括铰接连接和图像翘曲电子装置，允许基于离轴光学配置校正由光学系列和/或实施例的折叠引起的几何失真。
