Visible near-to-eye display technology based on nonlinear frequency conversion
Visible near-to-eye display technology based on nonlinear frequency conversion
We present a new approach to near-to-eye displays based on the use of non-colinear wave-mixing in a nonlinear lens material. Conventional approaches to near-to-eye displays—used in Augmented Reality (AR) use linear optics, and this creates challenges with transparency, scatter and eye-glow, with creating 3d wavefront effects and brightness. Our new approach combines two infrared beams to create an exit-pupil that sends light to the viewer’s eye. This approach allows us to create a fully transparent display, with high brightness, high optical efficiency, and the ability to fully control wavefront so as to create a virtual image at any desired distance. The human eye is extremely sensitive to light, and so we need only generate microwatts of light to create a bright image. We can create these outputs used pulsed microchip lasers which offer kW peak powers at mW level average powers.

Abstract
We present a new approach to near-to-eye displays based on the use of non-colinear wave-mixing in a nonlinear lens material. Conventional approaches to near-to-eye displays—used in Augmented Reality (AR) use linear optics, and this creates challenges with transparency, scatter and eye-glow, with creating 3d wavefront effects and brightness. Our new approach combines two infrared beams to create an exit-pupil that sends light to the viewer’s eye. This approach allows us to create a fully transparent display, with high brightness, high optical efficiency, and the ability to fully control wavefront so as to create a virtual image at any desired distance. The human eye is extremely sensitive to light, and so we need only generate microwatts of light to create a bright image. We can create these outputs used pulsed microchip lasers which offer kW peak powers at mW level average powers.
