1. A system, comprising:
a head wearable display device, comprising:
a waveguide display implemented at least one of in or on the head wearable display device, the waveguide display comprising:
a waveguide; and
an optical system, the optical system configured to:
receive image data corresponding to an image; and
project the image at least through the waveguide to be displayed to a user; and
at least one image monitor sensor, each of the at least one image monitor sensor implemented in or on the head wearable display device, each of the at least one image monitor sensor optically coupled to the waveguide or the optical system of the waveguide display, each of the at least one image monitor sensor configured to:
capture at least a portion of the image as a monitored image; and
output monitored image data corresponding to the monitored image; and
at least one processor, each of the at least one processor implemented in the head wearable display device or in a computing device separate from the head wearable display device, wherein the at least one processor is configured to:
receive the monitored image data from each of the at least one image monitor sensor; and
based at least on the monitored image data, determine whether the waveguide display displayed the image correctly,
wherein the at least one image monitor sensor comprises a given image monitor sensor optically coupled to the waveguide at a position on the waveguide above a user-viewable portion of the waveguide,
wherein the given image monitor sensor is configured to capture at least the portion of the image emitted from the position on the waveguide above the user-viewable portion of the waveguide.
