1. A wearable display device, comprising:
- left and right display lens systems configured for augmented reality imaging;
left and right imaging units of the respective left and right display lens systems configured to generate an augmented reality image, each of the left and right imaging units comprising;
an emitter structure configured to direct emit light;
optics configured to direct the light along a light path in the imaging unit;
a projection surface that the optics direct the light along the light path to illuminate, the projection surface being an electrically alterable mirror configured to scan in at least one dimension to reflect the light through an imaging optic that directs the light into a display optic; and
a reflective panel configured to reflect a portion of the light directed by the projection surface to illuminate a light sensor, the reflective panel positioned proximal to the imaging optic allowing the portion of the light to be reflected at a beginning position or an end position of the scan in the at least one direction of the projection surface.

Abstract
In embodiments of imaging structure emitter calibration, an imaging unit includes an emitter structure that direct emits light, and optics direct the light along a light path in the imaging unit to illuminate a projection surface. A reflective panel reflects a portion of the light to illuminate a light sensor. An imaging application receives the sensor data from the light sensor, where the sensor data corresponds to emitted light output from the emitter structure. The imaging application can then initiate a calibration input to the emitter structure to adjust the emitted light output from the emitter structure.
