Patent GB-2495398-A (GB)
Title: Optical waveguide and display device
Inventor: MASON STEPHEN PAUL
IPC: G02B27/00
Filed: 2012-10-04
Abstract: An optical waveguide 10 has at least two diffraction regions (14, 16 fig 1), one (14, fig 1) to diffract image bearing light along the waveguide 10 to expand it in a first dimension (15, fig 1) and to turn the image bearing light towards a second diffraction region (16, fig 1) which diffracts the image bearing light to expand it in a second dimension (17, fig 1) and to release it from the waveguide as a visible image (180, fig 1). The first region (14, fig 1) is formed by a first diffraction grating 18 embedded within the waveguide 10 and presents the same profile to light incident upon the grating 18 from above or below the grating 18. The grating 18 may have a symmetrical periodic square wave, sinusoidal or triangular profile. Polarisation of the image bearing light is rotated by similar amounts, but in opposite directions, by successive interactions with the first diffraction region (14, fig 1). This enables emitted image bearing light to present an image of substantially uniform intensity.
