Abstract:
A method and system for using laser-induced structures to direct light to exit the bottom of a leaky mode device, and further to divide leaky mode light into multiple orders, and to implement one or more pulsing/strobing patterns such that a field of view is increased for a viewer, or the view zone is increased for a viewer. A leaky mode device may comprise a substrate, a surface acoustic wave (“SAW”) transducer, a waveguide having a higher refractive index than the substrate, an input region for input light, and laser induced structures such as grating. The SAW transducer may be positioned on a top surface of the substrate, and may be configured to emit a SAW wave to propagate across the substrate. The waveguide may be positioned below the SAW. The input wave region may be configured to couple light onto the waveguide. When light is coupled onto the waveguide, the refractive index may change such that the light in the waveguide exits the waveguide as leaky mode light and interacts with the laser-induced grating, which is below the waveguide. The laser-induced grating is configured to divide the leaky mode light into multiple orders, each bent at a different angle.

Claim (Index 17):
A method for displaying an image, comprising:\n obtaining a representation of a virtual point; transmitting the representation of the virtual point to a transducer, wherein the transducer is configured to encode the virtual point as a surface acoustic wave (SAW) for propagation across a surface of a substrate in a leaky mode device comprising structures configured to divide leaky mode light into multiple orders; directing an input light to strobe at a first time and thereby illuminate the SAW, wherein the strobe at the first time is timed such that at least one of the orders resulting from interaction of first leaky mode light with the structures, wherein the first leaky mode light result from strobing the SAW at the first time, is directed toward a first view position; and directing the input light to strobe at a second time and thereby illuminate the SAW, wherein the strobe at the second time is timed such that at least one of the orders resulting from interaction of second leaky mode light with the structures, wherein the second leaky mode light results from strobing the SAW at the second time, is directed toward a second view position.
