Abstract: One example provides a head mounted display (HMD) device comprising a projection system and left eye and right eye display optical paths configured to transmit left eye and right eye images for viewing. The projection system comprises left and right display image projectors. The HMD device further comprises a display alignment tracker (DAT) system comprising a DAT optical path comprising left side and right side DAT optical paths. The DAT system further comprises a camera coupled to an output of the DAT optical path, and a visible light filter located along the DAT optical path. The HMD device further comprises a controller configured to control the projection system to output a fiducial image comprising a visible color of light transmitted by the visible light filter and to blank the visible color of the fiducial image from a fiducial portion of both the left and right eye images.
