摘要： We present optical systems suitable for focusing two substantially collimated beams or sheets of light propagating in different directions onto a common focal point. In some embodiments the optical systems comprise separate focusing elements for each beam or sheet of light, while in other embodiments the optical systems comprise a focusing element and a redirection element. The optical systems have particular application in the receive optics of infrared touch screens, where they enable the detection of additional light paths that assist in the determination of two or more simultaneous touch events.

摘要： This invention relates to an improved design for the transmit and receive optical elements of a waveguide-based optical touch screen sensor, where at least one converging lens is incorporated within the body of each transmit and receive element. The optical elements of the improved design are more mechanically robust, easier to incorporate into the touch screen assembly, and are less susceptible to stray light and the ingress of foreign matter. In one embodiment the converging lens collimates the light into a plane wave. In another embodiment the converging lens focuses the light to an external point. In yet another embodiment, each transmit and receive element also includes at least one diverging lens. The transmit and receive elements and associated waveguides preferably comprise photo-patternable polymers.

摘要： Planar lenses for integrated optics applications, in particular for use in optical touch screen sensors are disclosed. The disclosed planar lenses include a slab waveguide and an optical waveguide, preferably formed in unitary fashion, wherein the slab waveguide has a curved end face to focus light into or out of the optical waveguide, and wherein at least one additional lens is included within the slab waveguide. In one aspect of this disclosure, the additional lens is a diverging lens. In a second aspect the additional lens is a converging lens. The additional lens may match the acceptance angle of the optical waveguide to the curved end face of the slab waveguide. Alternatively, it may improve the tolerance of the planar lens to design or assembly errors and/or temperature variations. Preferably, the planar lenses are composed of a photo-patternable polymer, and the additional lenses are composed of air.
