description A wearable display includes left and right display lens systems each having imaging units configured for augmented reality imaging. The imaging units include an emitter structure, one or more optical elements, a display optic, an electrically alterable scanning optical element and a calibration light sensor. The emitter structure has one or more light sources configured to emit light. The optical elements direct the light along a light path in the imaging unit. The scanning optical element receives the light from the optical elements and directs it to the display optic. The scanning optical element scans in one or more dimensions to direct the light through an imaging optic that directs the light into the display optic. The calibration light sensor is located at a point along the light path between the emitter structure and the scanning optical element and receives a portion of light from one of the optical elements.
