Abstract
A projection system includes an illumination light source configured to emit an illumination light beam, a monitor light source configured to emit a monitor light beam, and a projector configured to project both the illumination light beam and the monitor light beam into a projected combined light beam. A first portion of the projected combined light beam is propagated over a first beam path in a first direction, causing an eye of a user to see a display image. A second portion of the projected combined light beam is propagated over a second beam path in a second direction, causing a monitor camera to capture a monitor image. The monitor image is analyzed to determine an orientation or a position of the monitor image. In response to determining that the monitor image is not properly oriented or positioned, an orientation or position of the projector or the illumination image is adjusted.
