1. An imaging apparatus for stereoscopic viewing, comprising:
a frame operable to be reshaped from a first shape to a second shape;
a left-eye imaging apparatus supported by the frame, wherein the left-eye imaging apparatus comprises a first projector and a first waveguide;
a right-eye imaging apparatus supported by the frame, wherein the right-eye imaging apparatus comprises a second projector and a second waveguide;
wherein the left-eye imaging apparatus and the right-eye imaging apparatus have a first relative alignment operable to convey stereoscopic virtual images to a viewer when the frame is in the first shape,
wherein the left-eye imaging apparatus and the right-eye imaging apparatus are arranged at a second relative alignment when the frame is in the second shape; and
an adjustment mechanism comprising an actuator operable to respond to a reshaping of the frame, wherein the actuator is operable to change an angular alignment of the first projector relative to the first waveguide and the frame and/or the second projector relative to the second waveguide and the frame to restore the first relative alignment of the left-eye imaging apparatus and the right-eye imaging apparatus while the frame is in the second shape.
