    Abstract: A device for reducing laser speckle using a micro scanner and a holographic diffuser. The micro scanner includes a first transparent optical substrate with an input surface and an output surface and a second transparent optical substrate with an input surface and an output surface and a variable refractive index medium sandwiched between the output surface of the first substrate and the input surface of the second substrate. Transparent electrodes are applied to the output surface of the first substrate and the input surface of the second substrate. The electrodes are coupled to a voltage generator. The input surface of the first substrate is optically coupled to a laser source. The input surface of the second substrate is configured as an array of prismatic elements. At least one of the input surface of the first substrate or the output surfaces of the second substrate is planar.

    Abstract: There is provided a wearable display comprising at least one Switchable Bragg Grating (SBG) device recorded in at least one Holographic Polymer Dispersed Liquid Crystal (HPDLC) layer. Each HPDLC layer is sandwiched between first and second transparent plates to which transparent electrodes have been applied. Each SBG device is characterised in that it provides a grating in a separate switchable region and is clear elsewhere. Each SBG device has a diffracting state and a non diffracting state. The transparent plates and HPDLC layers form a laminar structure which functions as a light guide. In one embodiment of the invention the display magnifies and forms a virtual image of information provided by an external image generator. In one embodiment of the invention the display and forms a virtual image of an image of information encoded in the SBG device.

    Abstract: Light from an image displayed on a display screen 10 is transmitted to an observer's eye 11 by way of a dynamic optical element 12 (such as a spatial light modulator or an electrically switchable holographic composite) which acts as a lens. The characteristics of the dynamic optical element 12 can be altered so that it acts sequentially to direct light of different colors to the observer's eye. In one optional embodiment emitters 17 on the display screen 10 emit infra-red radiation which is projected by the dynamic lens 12 as a broad wash onto the eye 11. Infra-red radiation reflected back from the eye 11 is focussed by the dynamic lens 12 onto detectors 18 also provided on the display screen 10. The detectors 18 are thus able to sense the direction of eye gaze, and the dynamic lens 12 is controlled in dependence on this to create an area of high resolution in an area of interest centered on the direction of gaze, which is moved to follow the eye gaze as its direction alters. Other than in the area of interest, the dynamic lens 12 has a relatively low resolution.
