OFFSETTING IMAGE LIGHT ABERRATION DUE TO WAVEGUIDE MOVEMENT IN DISPLAY ASSEMBLIES

A display assembly monitors movements in a waveguide assembly and corrects for aberrations in image light caused by the monitored movements. For example, an artificial reality headset may include a display assembly that monitors for changes in shape or displacement of waveguide assemblies that gener...

More Information
Summary:A display assembly monitors movements in a waveguide assembly and corrects for aberrations in image light caused by the monitored movements. For example, an artificial reality headset may include a display assembly that monitors for changes in shape or displacement of waveguide assemblies that generate three dimensional images for display with a real world environment. The display assembly includes movement sensors (e.g., piezoelectric movement sensors) coupled to the waveguide assembly. The movement sensors monitor the movement of the waveguide assembly and provide the monitored movement to a display controller that generates instructions for correcting aberrations in the image light.
