Temporal Phase Unwrapping Based on Unequal Phase-Shifting Code

IEEE Transactions on Image Processing, 2023
In fringe projection profilometry (FPP) based on temporal phase unwrapping (TPU), reducing the number of projecting patterns has become one of the most important works in recent years. To remove the $2\pi $ ambiguity independently, this paper proposes a TPU method based on unequal phase-shifting code.

Temporal phase unwrapping using orthographic projection

Optics and Lasers in Engineering, 2017
This paper proposes a novel temporal phase unwrapping method which is a generalization of the three commonly proposed approaches: hierarchical, heterodyne, and number theoretical phase unwrapping. The proposed unwrapping method is based on the orthographic projection of wrapped phases from the measurement space to the space of co-dimension 1.
