Phase Unwrapping Algorithm with Zernike Polynomials

A new phase unwrapping algorithm is presented. It is mainly used in the cases of optical smooth surface with few low modulation and speckle points, no heavy noise. The algorithm is based on Zernike polynomials. It fits the data into Zernike polynomials and filters the unreasonable data through a threshold. The new algorithm shows high speed calculation.
