Claim:
1. An optical apparatus comprising: a touch substrate; a waveguide layer, disposed on the touch substrate, the waveguide layer comprising a plurality of waveguides; an optical output structure, which is disposed on the waveguide layer and is configured to output light propagating in the plurality of waveguides at touched locations of the touch substrate; a gap layer disposed between the waveguide layer and the optical output structure and providing a gap between the waveguide layer and the optical output structure; an optical system, which projects light output by the optical output structure; and a transparent fixing member disposed on the gap layer and over the optical output structure; wherein a first side of the touch substrate is in close contact with a second side of the waveguide layer, such that there is no gap between the first side of the touch substrate and the second side of the waveguide layer; wherein both the touch substrate and the waveguide layer are elastically deformable by external pressure; and wherein a light exit surface of the transparent fixing member is inclined, such that light output by the optical output structure is perpendicularly incident on the light exit surface of the transparent fixing member.
