Abstract
A head-mounted display apparatus for a viewer has an optical imager having a display generator that is energizable to emit image-bearing light in a first direction and a prism that is configured to redirect the generated light in a second direction that is toward the viewer's eye and orthogonal to within +/−30 degrees relative to the first direction. A housing is configured to form a sealed chamber that encloses at least the display generator of the optical imager and to expose at least a portion of the prism extended from the sealed chamber. A releasable coupling formed onto a cover element of the sealed chamber is configured to cooperate with a mounting fixture formed on headgear worn by the viewer for mounting the housing and suspending the exposed portion of the prism into a field of view of the viewer's eye.
