Abstract

Optical techniques avoid mechanical contact with the cartilage and therefore its subsequent deformation. They are well suited for the 3-D vision of articular surfaces shape. Three techniques which have in common the fact to produce contour lines on the surface are reviewed. Holographic interferometry (HI) by refractive index change, by spatial frequency modulation and moire topography are compared with respect to the particular application to anatomic preparations. With HI by spatial frequency modulation the major problem encountered is the dehydration of the specimen which induces its deformation. HI by refractive index change involves level lines with a depth resolution easily adaptable to the curvature of the surface to be studied. The most effective technique is moire topography and we show that the result obtained is within an accuracy acceptable with respect to the wide biological variations encountered. This stays even when the contour lines do not represent strict level lines.
