Despite the widespread exploration and application of Digital Lensless Holographic Microscopes (DLHMs), there remains a scarcity of portable implementations tailored specifically for fieldwork applications such as remote diagnosis, medical analysis, on-field biological sample study, and even outreach and academic demonstrations. This paper introduces a portable prototype that assembles a Digital Lensless Holographic Microscope (DLHM) with a smartphone camera designed specifically for such fieldwork scenarios. The …
