Abstract

In this study, we report spatial resolution enhancement and image quality improvement of a digital holographic microscopy using speckle patterns generated from a moving diffuser. In this method, speckle patterns are produced by moving a diffuser in the in-plane directions and incident on an object. In comparison with other methods for generating speckle illuminations, it realizes a simple and low-cost optical setup in digital holographic microscopy.
