在这项研究中,我们报告的空间分辨率增强和图像质量改善的数字全息显微镜使用散斑图案产生的移动扩散。在该方法中,散斑图案通过在面内方向上移动漫射器并入射到物体上来产生。与其他产生散斑照明的方法相比,该方法实现了数字全息显微术中简单、低成本的光学装置。
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.
