Optical device, and virtual image display

摘要

An image display device with an image display element; an optical system; an optical waveguide having a light incident port at a first portion of the optical waveguide and a light outgoing port at a second portion of the optical waveguide, the optical waveguide configured to (a) receive light from the image display element via the optical system and (b) output the light via the light outgoing port; a light shielding element; a first element that deflects light received through the first portion of the optical waveguide; and a second element that deflects light conveyed in the optical waveguide to output the light through the second portion of the optical waveguide, wherein, the first portion and the second portion are at different positions along the optical waveguide, and the first element is between the light incident port of the optical waveguide and the light shielding element.
