Comparing of phase shifting method and one-dimensional continuous wavelet transform method for reconstruction using phase-only information

Authors: GÜLHAN USTABAŞ KAYA, ZEHRA SARAÇ

Abstract: The one-dimensional continuous wavelet transform method has some advantages in hologram reconstruction, when used in the only phase, compared with the phase shifting method. This paper aims to discuss these advantages. One advantage is related to image quality. Another advantage is less power spent and saving time, because the one-dimensional continuous wavelet transform method uses only one hologram and the phase shifting method uses four holograms for recording and reconstruction processes. One final advantage is that the one-dimensional continuous wavelet transform method can also be used in real-time applications. Within the context of the ongoing optimization studies, this study will make a significant contribution to the literature because of these mentioned advantages.
