| 摘 要： | 基于波相差理论，分析了数字全息记录过程中所用参考光可能存在的波面畸变；以傅里叶变换型数字全息为例，详细讨论了具有波面畸变的平面参考光对数字全息记录与再现的影响，外提出采用修正波面的再现光消除参考光波面畸变影响的方法．理论分析和模拟结果表明，这种方法能有效消除参考光波而畸变带来的影响，大幅度提高再现像的像质．

| Abstract: | Wavefront aberrations of the reference beam in holographic recording is analyzed based on aberration theory. As an example here, influences of this kind of aberrations on reconstructed results of Fourier digital holograms are discussed. Analyses and simulations reveal that the reconstructed image will be blurred if the aberrations is ignored in digital reconstruction. And a feasible method for eliminating this disturbance by constructing a corrected illumination beam is proposed and demonstrated. |
