Abstract
This disclosure describes a wearable display system configured to project light to the eye(s) of a user to display virtual (e.g., augmented reality) image content in a vision field of the user. The system can include light source(s) that output light, spatial light modulator(s) that modulate the light to provide the virtual image content, and an eyepiece configured to convey the modulated light toward the eye(s) of the user. The eyepiece can include waveguide(s) and a plurality of in-coupling optical elements arranged on or in the waveguide(s) to in-couple the modulated light received from the spatial light modulator(s) into the waveguide(s) to be guided toward the user's eye(s). The spatial light modulator(s) may be movable, and/or may include movable components, to direct different portions of the modulated light toward different ones of the in-coupling optical elements at different times.
