Abstract

This research introduces an innovative quantitative phase microscopy system employing a phase-contrast configuration. Azobenzene liquid crystal material serves as the phase-contrast modulator, and a polarization-sensing camera acts as the detector, capturing four-shifted images in a single shot. The quantitative phase information is then retrieved through a four-step phase-shifting algorithm. Our study establishes a correlation between the four detected polarization states and the Pancharatnam-Berry geometric phase characteristics of the liquid crystal material. This research holds significance as it advances our comprehension of single-shot QPM utilizing geometric phase and holds the potential to revolutionize real-time monitoring and 3D visualization across diverse biological scenarios.
