Abstract
Phase retrieval algorithm is gradually applied to the terahertz in-line digital holography, as its effectiveness in the removal of the zero-order diffraction light and twin image. Based on the experiments, the reconstruction results of the double-exposed phase retrieval algorithm are obtained which demonstrate that the method can improve the quality of reconstructed images, compared to the angular spectrum method. Furthermore, the influence of the superimposed frame number of the holograms in double-exposed phase retrieval algorithm is discussed. The result shows that the recording time can be reduced by reasonably decreasing the frames of the holograms and it contributes to real-time imaging and the algorithm practicality is also further improved.
