DIFFRACTIVE OPTICAL ELEMENTS USED FOR AUGMENTED OR VIRTUAL REALITY

摘要

Configurations are disclosed for presenting virtual reality and augmented reality experiences to users. The system may comprise an image-generating source to provide one or more frames of image data in a time-sequential manner, a light modulator configured to transmit light associated with the one or more frames of image data, a substrate to direct image information to a user's eye, wherein the substrate houses a plurality of reflectors, a first reflector of the plurality of reflectors to reflect transmitted light associated with a first frame of image data at a first angle to the user's eye, and a second reflector to reflect transmitted light associated with a second frame of the image data at a second angle to the user's eye.

主权项

1. A system for displaying virtual content to a user, comprising:
a transmissive beam splitter substrate having an entrance to receive light and a number of internal reflective or diffractive surfaces angled with respect to the entrance to redirect at least a portion of the light received at the entrance transversely outward of the transmissive beam splitter substrate toward an eye of the user, wherein the number of internal reflective or diffractive surfaces includes a plurality of transverse reflective and/or diffractive surfaces spaced along a longitudinal axis of the transmissive beam splitter substrate, each of the transverse reflective and/or diffractive surfaces angled or angleable with respect to the entrance to redirect at least a portion of the light received at the entrance transversely outward of the transmissive beam splitter substrate along an optical path toward an eye of the user; a light generating system to transmit light to the transmissive beam splitter; and a local controller communicatively coupled to the display system to provide image information to the display system, the local controller comprising at least one processor, and at least one nontransitory processor readable media communicatively coupled to the at least one processor, the at least one nontransitory processor readable media which stores at last one of processor-executable instructions or data, which when executed by the at least one processor causes the at least one processor to at least one of process, cache, and store data and provide the image information to the display to produce at least one of a virtual or an augmented reality visual experience to the user.
