We fabricate a head-mounted display (HMD) providing a gradation VR image generated at the surface by using the excitation of the guided mode in a TiO2-slanted nanograting layer. In the TiO2 layer, the beam is waveguided along the short axis direction of the grating at a specific injection angle Θ. On the surface of the layer, a beam consisting of leakage generated during the waveguide is emitted. It generates an intensity gradient image for the waveguide direction. In this work, we convert this gradation image to VR by using another coupler. Finally, the obtained gradation VR image is also discussed.
