Quantitative polarized phase microscopy for birefringence imaging

Optics Express, 2007
A novel application of quantitative phase imaging under linearly polarized light is introduced for studying unstained anisotropic live cells. The method is first validated as a technique for mapping the two-dimensional retardation distribution of a well-characterized optical fiber and is then applied to the characterization of unstained isolated ...

Breakthroughs in Photonics 2013: Quantitative Phase Imaging: Metrology Meets Biology

IEEE Photonics Journal, 2014
Quantitative phase imaging (QPI) is an emerging optical approach that measures the optical path length of a transparent specimen noninvasively. Therefore, it is suitable for studying unstained biological tissues and cells with high sensitivity and ...

Quantitative phase imaging using grating-based quadrature phase interferometer [PDF]

, 2007
In this paper, we report the use of holographic gratings, which act as the free-space equivalent of the 3x3 fiber-optic coupler, to perform full field phase imaging.
