1. A worn display for a user having eyes, the worn display comprising:
- a projector; and
at least one diffraction grating member configured to be wearable and physically separate from the projector and physically free from the projector across rotational movement of the at least one diffraction grating member, the diffraction grating member having an input end for receiving a collimated image from the projector, and a combiner end for providing the collimated image received at the input end to the eyes of the user and wherein the light received from an outside scene is viewable through the combiner end, the at least one diffraction grating member extending from the input end to the combiner end, wherein the input end is configured to be disposed to receive the collimated image from the projector in a position unobstructed by the user and the combiner end is configured to be disposed in front of the eyes.

Abstract
A worn display, includes a projector and at least one wearable diffraction grating member. The member includes an input end for receiving an image from a projector and a combiner end for receiving light from a scene and providing the image received at the input end and the light received from the outside scene to the user. The worn display can be used in aircraft applications to provide guidance information to a pilot. The diffraction grating member can have periscopic characteristics.

17. A method of providing guidance information to at least one eye of a user using a display projector comprising a display and a worn device, the method comprising:
-
providing a collimated or near collimated image indicative of the guidance information from the display using a diffraction grating member of the worn device configured so that a first end of the diffraction grating member of the worn device can be provided in front of the eye of the user and a second end of the diffraction grating member receives the collimated or near collimated image, wherein the first end receives light from a real world scene, wherein the second end is disposed in a position unobstructed by the user, wherein the diffraction grating member is physically separate from the display projector and physically free from the display projector across rotational movement of the diffraction grating member when worn by the user; and combining light received from a real world scene at the first end with the collimated or near collimated light using the diffraction grating member. - View Dependent Claims (18, 19, 20)
