    Abstract: A display device comprises red, green, and blue laser sources; a Spatial Light Modulator (SLM) comprising at least one diffraction grating (10) recorded in an electrically variable refractive index material; a control circuit coupled to the SLM; an image generator; and a light stop (20). The SLM is illuminated with a red light at a first angle, green light at a second angle and blue light at a third angle which defines a viewing direction. Diffracted red and green light and undiffracted blue light emerge from the SLM in the viewing direction. Undiffracted red and green light and diffracted blue light are blocked by the stop after emerging from the SLM. I one embodiment, the SLM comprises one Bragg grating which diffracts red and green light into the viewing direction and the blue light away from the viewing direction. In another embodiment, the SLM comprises superimposed red, green and blue diffracting Bragg gratings.

    Abstract: An improved door viewer providing a large area viewable image is disclosed, comprising a wide-angle lens (1), a multiple reflection lens (2) and a diffusing screen (4). The multiple reflection lens comprises a first transmitting surface (12) operative to admit external scene light, second (24a) and third (24b) transmitting surfaces for transmitting light towards a viewer and first (21a) and second (23a) reflecting surfaces. The second reflecting surface surrounds the first transmitting surface. The first reflecting surface surrounds the second transmitting surface. The third transmitting surface surrounds both the first reflecting surface and the second transmitting surface. Low incidence angle light entering first transmitting surface passes through the second transmitting surface towards the viewer. High incidence angle light entering the first transmitting surface, is reflected at the first reflecting surface, reflected at the second reflecting surface, and passes through the third transmitting surface towards the viewer. Said ray paths traverse at least one light-refracting medium.

    Abstract: A layer (14) of optically active material overlaps the mode field of a single-mode optical waveguide (10) and has regions (16, 17) to which electric fields (E1, E2) can be applied by way of respective electrodes (18, 19) so as to vary the refractive index of the layer (14) in those regions. The regions (16, 17) are spaced apart longitudinally of the waveguide (10), and the fields (E1, E2) are so arranged that they extend at different angles to an interface (13) between the waveguide (10) and the layer (14) and act sequentially upon different polarisation components of radiation propagating along the waveguide (10). In one arrangement, the fields (E1, E2) are orthogonal to one another. In an alternative arrangement, a third field (E3) can be applied to a further longitudinally-spaced region of the layer (14) and the three fields (E1, E2 and E3) are arranged at (120°) to one another.

    Abstract: An optical display comprises: a first waveguide comprising a first surface and a second surface, an input coupler, a fold grating, and an output grating. The input coupler receives collimated first wavelength light from an Input Image Node causes the light to travel within the first waveguide via total internal reflection between the first surface and the second surface to the fold grating. The fold grating provides pupil expansion in a first direction directs the light to the output grating via total internal reflection between the first surface and the second surface. The output grating provides pupil expansion in a second direction different than the first direction and causes the light to exit the first waveguide from the first surface or the second surface. At least one of the input coupler, fold grating and output grating is a rolled k-vector grating, and the fold grating is a dual interaction grating.
