Description

Three optical, noncontact, automated experimental techniques for determining the topography of object surfaces were assessed. The main objective was to test the limitations of three experimental techniques: projection moire, stereo imaging, and phase-measuring profilometry. Phase-measuring profilometry is the most promising of the three techniques for mapping rock fracture surfaces automatically, accurately, quickly, and with high resolution. The experimental set-ups used to assess these different techniques are similar, and they require essentially the same equipment. It is relatively easy and inexpensive to go from one experimental set-up to another. Also, the experience gained in implementing one experimental technique is often applicable ... continued below

Also, the experience gained in implementing one experimental technique is often applicable in another, although the basic principles of each experimental technique are sometimes very dissimilar.
