with sinusoidal intensity variations along the radial
direction. A new algorithm is also proposed for retrie-
ving the phase information from the circular fringes.
The proposed CFFTP has been evaluated for varying
dynamic ranges and fringe frequencies. It is found
that the proposed algorithm significantly outperforms
the existing LFFTP, particularly at high dynamic ran-
ges and low fringe frequencies. In the future work,
we plan to evaluate the proposed CFFTP method for
the 3D profiling of the real-world objects.
