Abstract
An example system includes a photo detector and a phase detector. The photo detector may detect a facet of a rotating mirror, the rotating mirror having at least two facets. The phase detector may detect a phase of a motor driving rotation of the rotating mirror. The example system may also include a processor to determine a phase relationship between the facet detected by the photo detector and the phase of the motor detected by the phase detector.
