Abstract

For lensless digital in-line holographic microscopy a new state-of-the-art spatial resolution corresponding to an NA of 0.8 is shown based on the tile superposition propagation. The result is proved using a common glass sample carrier with a refraction index of 1.52. Single-shot high-resolution imaging is possible by suppression of coherent reflections in an optimized arrangement using partially coherent laser light illumination.
