Abstract: There is provided a colour sequential illumination device comprising in series: first and second light sources; a condenser lens; and a grating device. The grating device comprises at least one Bragg grating. The condenser lens directs light from the first and second sources into the grating device at first and second incidence angles respectively. The grating device diffracts light from the first and second sources into a common direction. Desirably, the Bragg gratings are Electrically Switchable Bragg Gratings. In one embodiment of the invention the light sources are Light Emitting Diodes. Alternatively lasers may be used.

Abstract: A general purpose sensor architecture integrating a surface enhanced Raman spectroscopy (SERS) substrate, a diffractive laser beam delivery substrate and a diffractive infrared detection substrate is provided that can be used to implement a low-cost, compact lab-on-a-chip biosensor that can meet the needs of large-scale infectious disease testing. The sensor architecture can also be used in any other application in which molecules present in the liquid, gaseous or solid phases need to be characterized reliably, cost-effectively and with minimal intervention by highly skilled personnel.

Abstract: There is provided an object tracker having: a first waveguide; a source of illumination light; a detector optically coupled to the waveguide; and at least one grating lamina formed within the waveguide. Illumination light propagating along a first optical path from the source to an object in relative motion to the object tracker. Image light reflected from at least one surface of an object is deflected by the grating lamina into a second optical path towards the detector.

Abstract: A waveguide display having an input image generator providing image light projected over a field of view; a waveguide having first and second external surfaces; and at least one grating optically coupled to the waveguide for extracting light towards a viewer. The waveguide has a lateral refractive index variation between said external surfaces that prevents any ray propagated within the waveguide from optically interacting with at least one of the external surfaces.
