A holographic image projection and tracking system has been developed which can automatically map a surface with high precision. To illustrate the potential usefulness of this technique to bio-medical applications, point coordinate data for preselected points and automatically scanned surface profile data has been taken of a skull geometry model. The model is representative of the average American male. System design studies on this holographic technique show that 1) dimensions of objects of the order of 1 meter in size can be produced from their image to an accuracy of 1 part in 10 and 2) the precise location of the image surface can unambiguously be determined for even matte, feature-less surfaces without the need for surface preparation. The skull model data and suggestions for other bio-medical applications are presented.
