Photonic Spin-Hall Differential Microscopy

This is the authors' abstract. We don't add key points for this paper.

The visualization of objects such as transparent living cells and tissues plays an important role in biological research. However, weak scattering and absorption of ``phase objects'' make it challenging to obtain high-contrast images, and phase-contrast techniques are needed. This study proposes differential microscopy based on the photonic spin Hall effect at a simple glass interface. The combination of the photonic spin Hall effect and a bright-field microscope can perform spatial differentiation on the phase distribution, which leads to a low-cost differential interference contrast (DIC) system.
