Abstract
A worn display, such as a head worn display, includes a projector and a periscopic system configured to be wearable. The periscopic system includes at least one 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 head worn display can be used in aircraft applications to provide guidance information to a pilot.
