波面重建 meaning in Chinese
wave-front reconstruction
Examples
- Firstly the phase is extracted from interferogram by filtering and displacing frequency spectrum . then the wavefront and the line integral density are recovered by using fft or polynomial fitting method . lastly the radial local density distribution is calculated from the fitting curve of line integral density by the abel inversion
首先对干涉图进行频谱滤波，用频谱移频法从干涉图中提取相位，然后用快速傅立叶变换或多项式拟合实现波面重建，计算线积分密度，再利用abel积分变换从线积分密度的拟合曲线中反演径向体密度分布。
