The illuminator member has a support structure (30) for retaining the illuminator member in position proximate the area to be imaged. A reference (22) is coupled to the support structure (30) of the illuminator member and disposed within the area to be imaged. At least one light source (24) is coupled to the support structure (30) of the illuminator member for directing imaging illumination toward the area to be imaged. A camera (12) records an image from within the area to be imaged using the imaging illumination from the illuminator member, wherein the image comprises the reference (22).
