  360-degrees digitalization of three-dimensional (3D) solids using a projected
light-strip is a well established technique. These profilometers project a
light-strip over the solid under analysis while the solid is rotated a full
revolution. Then a computer program typically extracts the centroid of this
light-strip, and by triangulation one obtains the shape of the solid. Here
instead of using intensity-based strip centroid estimation, we propose to use
Fourier phase-demodulation. This 360-degrees profilometer first constructs a
carrier-frequency fringe-pattern by closely adding individual light-strip
images. Secondly this high-density fringe-pattern is phase-demodulated using
the standard Fourier technique.
