| contents | Digital holography (DH) enables non-contact, noninvasive 3D imaging of transparent and moving microscopic samples by capturing amplitude and phase information in a single shot. In this work, we present a compact, low-cost, real-time smartphone-based DHM system accelerated by GPUs. The system comprises a 3D-printed optical system using readily available image sensors and lasers, coupled with an Android app for hologram reconstruction, extracting amplitude and phase information. Results show a frame rate improvement of approximately 1.65x compared to a CPU-only system. This inexpensive, compact DHM, combining 3D-printed optics and smartphone-based reconstruction, offers a novel approach compared to existing systems and holds promise for fieldwork and remote diagnostics. |
