Abstract

Lensless digital holography can reconstruct the intensity and phase of an object located behind a diffuser. However, the image quality of reconstructed images is dependent on the distance between the diffuser and the image sensor or between the diffuser and the sample. For this study, we reconstruct the object intensity by changing the distance between the sample and the diffuser. Then we investigate the image quality of reconstructed images.
