Claim:
1. An imaging unit, 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; 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; and an imaging application configured to receive sensor data from the light sensor, the sensor data corresponding to emitted light output from the emitter structure, and the imaging application further configured to initiate a calibration input to the emitter structure to adjust the emitted light output from the emitter structure.
