Abstract:

Described herein is a polarization microscope that uses spectral-encoding of the polarization state for cellular imaging. The spectral-encoded polarization microscope is both sufficiently fast for cellular imaging and is compatible with high extinction optics required to image molecular structures and assemblies. The spectral-encoded microscope allows for the polarization state of light presented to the specimen to sample discrete states over the entirety of the Poincaré sphere while simultaneously giving a null measurement of the observed cellular birefringence. Sampling over the entire Poincaré sphere allows the microscope to determine of specimen phase retardation due to both linear and circular birefringence. The spectral-encoded polarization microscope can be operated in a slightly off-null state that will improve signal-to-noise.
