In this work, we present a novel Panoramic Fringe Projection system (PFP) to retrieve the three-dimensional topography of quasi-cylindrical objects along their full length and around the entire circumference. The proposed procedure uses a 45° concave conical mirror to project a circular sinusoidal fringe pattern onto a specimen placed coaxially to the mirror, and at the same time, to image the modulated fringe pattern diffused from the object surface. In order to obtain the required sensitivity, an axicon is used to create a divergent fringe pattern with constant pitch. By processing the phase map, information on the radius over the full 360° surface of the sample is obtained. To verify the feasibility of the PFP measurement, a target sample with known shape-discontinuities has been tested. The proposed method demonstrated to be able to retrieve the full topography of complex shaped samples for a large variety of applications in the industrial and biomedical fields.
