22 February 2013 Quantitative birefringence imaging of biological samples using quadri-wave interferometry
Author Affiliations +
We describe a new technique based on the use of a high-resolution quadri-wave lateral shearing interferometry wave front sensor to perform quantitative linear birefringence measurements on biological samples. The system combines quantitative phase images with different excitation polarizations to create birefringence images. This technique is fast and compatible with living samples. It gives information about the local retardance and structure of their anisotropic components.
