Abstract
An eyepiece for projecting an image light field to an eye of a viewer for forming an image of virtual content includes a waveguide, a light source configured to deliver a light beam to be incident on the waveguide, a controller coupled to the light source and configured to modulate an intensity of the light beam in a plurality of time slots, a dynamic input coupling grating (ICG) configured to, for each time slot, diffract a respective portion of the light beam into the waveguide at a respective total internal reflection (TIR) angle corresponding to a respective field angle, and an outcoupling diffractive optical element (DOE) configured to diffract each respective portion of the light beam out of the waveguide toward the eye at the respective field angle, thereby projecting the light field to the eye of the viewer.
