Abstract:
An optical system that deploys micro electro mechanical system (MEMS) scanners to contemporaneously generate CG images and to scan a terrain of a real-world environment. An illumination engine emits a first spectral bandwidth and a second spectral bandwidth into an optical assembly along a common optical path. The optical assembly then separates the spectral bandwidth by directing the first spectral bandwidth onto an image-generation optical path and the second spectral bandwidth onto a terrain-mapping optical path. The optical system deploys the MEMS scanners to generate CG images by directing the first spectral bandwidth within the image-generation optical path and also to irradiate a terrain by directing the second spectral bandwidth within the terrain-mapping optical path. Accordingly, the disclosed system provides substantial reductions in both weight and cost for systems such as, for example, augmented reality and virtual reality systems.

Claim (Index 16):
The NED device of  claim 10 , wherein the optical assembly comprises:\n a polarizing beam splitter (PBS) to reflect a first polarization state of EM radiation and transmit a second polarization state of EM radiation; a first waveplate disposed between the PBS and at least one MEMS scanner, wherein the EM radiation propagates through the PBS toward the first waveplate in the second polarization state and is transmitted through the first waveplate toward the at least one MEMS scanner, and wherein the EM radiation propagates from the first waveplate to the PBS in the first polarization state and is reflected by the PBS toward the display; a wavelength selective reflector disposed between the display and the PBS, the wavelength selective reflector configured to transmit the first bandwidth into the display and to reflect the second bandwidth back toward the PBS; and a second waveplate disposed between the PBS and the wavelength selective reflector, wherein the second bandwidth propagates from the second waveplate to the PBS in the second polarization state and is transmitted through the PBS to irradiate the object within the real-world environment.
