Label-free nanoscopy enabled by coherent imaging with photonic waveguides

摘要

In this project it was found that Fourier ptychographic microscopy can be improved far beyond its conventionallimits via waveguide-based optical systems. Extensive in silico studies showed that images obtained on highrefractiveindex material waveguide chips in conjunction with hyperspectral illumination light and finely designedwaveguide geometries can be combined via a modified phase-retrieval algorithm to yield a resolution below 150nm.
