Low-coherence wavelength shifting interferometry for high-speed quantitative phase imaging.


We propose low-coherence wavelength shifting interferometry and demonstrate its application to quantitative phase imaging of dynamic specimens. By shifting the source wavelength, multiple interferograms of the sample can be acquired at different spectral bands. A sample phase is thus encoded in the phase step between consecutive acquisitions. For the… (More)
