Abstract
The studied object is illuminated by a light sheet. The fringe produced on its surface is distorted proportionally to the local depth. Scanning the whole surface and integrating the values of the depth provides the total volume. The automation of the process includes the reduction of the fringe width to one pixel, the calibration of the magnification and the completion of the fringe discontinuities.
