Query: Co-Phased 360-Degree Profilometry of Discontinuous Solids with
  2-Projectors and 1-Camera   Here we describe a co-phased 360-degree fringe-projection profilometer which
uses 2-projectors and 1-camera and can digitize discontinuous solids with
diffuse light surface. This is called co-phased because the two phase
demodulated analytic-signals from each projection are added coherently. This
360-degree co-phased profilometer solves the self-generated shadows cast by the
object discontinuities due to the angle between the camera and the single
white-light fringe projector in standard profilometry.
