Abstract

A scanned beam imaging system including a radiation source configured to provide a beam of radiation, a movable element configured to direct the beam of radiation onto a scanned area, and a collector configured to receive radiation returned from the scanned area. The imaging system further includes a housing that houses the movable element therein and a reference mark coupled to or received in the housing. The reference mark is positioned such that at least part of the radiation from the radiation source is directable at the reference mark.
