Fig. 4.

Captured photographs of holographic images processed with various holographic correction modes are demonstrated. From the first column, the target intensity, the photographs of holographic images after SPH correction, SPH&CYL correction, and SPH&CYL + SV correction are provided sequentially. The captured results are digitally combined with 25 different hologram frames to reduce speckle noise and emphasize the degradation in image quality in the presence of undesirable aberrations. We ruled out the demonstration of uncorrected holographic image as the content can hardly be recognized.
