Abstract
A wearable display device and a calibration method for the wearable display device are provided. The wearable display device or its component(s) may exhibit optical throughput dependent on beam angle or beam coordinate at the eyebox. The linear or angular dependencies of throughput may be accounted for when generating an image to be displayed, to lessen or offset these dependencies during operation of the wearable display.
