Image Contrast Improvement in Interference-Dark-Field Digital Holographic Microscopy
Photonics, 2021 Conventional dark-field digital holographic microscopy (DHM) techniques require the use of specialized optics, and, thus, obtaining dark-field images with high contrast has a high cost. Herein, we propose a DHM system that uses an interference-dark-field
