SEE-THROUGH DISPLAY OPTIC STRUCTURE

摘要

An optical structure useful in a see-through head mounted display apparatus is provided. A first and a second partially reflective and transmissive elements are configured to receive the output of any number of optical sources via an optical element. Each reflective and transmissive element is positioned along an optical viewing axis for a wearer of the device with an air gap between the elements. Each reflective and transmissive element has a geometric axis which is positioned in an off-axis relationship with respect to the optical viewing axis. The off-axis relationship may comprise the geometric axis of one or both elements being at an angle with respect to the optical viewing axis and/or vertically displaced with respect to the optical viewing axis.

1. An optical display system operable to output an image to an optical viewing axis, comprising:
an image source; a first optical element positioned along the optical viewing axis and having a first geometric axis at the optical viewing axis that is positioned off-axis with respect to the optical viewing axis; a second optical element positioned along the optical viewing axis and having a second geometric axis at the optical viewing axis that is positioned off-axis with respect to the optical viewing axis.
