Abstract
An apparatus, system, and related methods for the conversion of a regular bright-field microscope into a PS-QPI (Polarization-Sensitivity and Quantitative Phase Imaging) microscope system. A regular bright-field microscope is converted by insertion of a polarizing element in the illumination path and a Fresnel biprism in the image space of the system. The converted system is suitable for real-time quantitative PS phase imaging in a broad number of biological applications aimed at understanding cell growth and dynamic changes occurring during physiological processes, as well as identification of cell/tissue screening and diagnosis.
