基于泽尼克多项式的相位去包裹算法

Phase Unwrapping Algorithm with Zernike Polynomials

研究了泽尼克(Zernike)多项式用于波面数据拟合和相位去包裹方法,针对光滑表面以及由于少数低调制度点、散斑点、噪声等引起的相位去包裹不连续情形,采用Zernike多项式对误差点区域进行拟合,通过阈值的设置,将误差点清除并予以拟合.该方法具有计算快速的特点.

A new phase unwrapping algorithm with Zernike Polynomials to fit the data into a continuum wave is presented. It is mainly used in the cases of optical smooth surface with few low modulation, speckle points and noise. The algorithm is based on Zernike polynomials and filters the unreasonable data through a threshold. The new algorithm shows high speed calculation.
