| 摘 要： | 利用数值仿真的方法详细的分析了近场强度分布对线性相位反演算法复原效果的影响.对近场强度分布分别为倾斜、环形和高斯随机型的情况下的复原结果与光强均匀时的复原结果进行对比,结果表明像倾斜型这种大部分为奇函数的近场强度分布对复原效果的影响比较恶劣;而像环形、随机型这样的偶函数或大部分为偶函数的近场强度分布对复原效果的影响则不...

| Abstract: | The effect of the near-field intensity distribution on linear phase retrieval is analyzed in detail.Reconstructed results in cases of three distributions-tilt,ring,random-type near-field intensity distribution are compared with uniform intensity respectively.The results show that the reconstructed effect of tilt-type which is composed of odd functions is adverse;while the reconstructed effect of ring and random-type which is composed of even functions is not large.Especially when the spatial frequency was h... |
