Quantitative phase imaging with spectral-domain optical coherence phase microscopy

Spectral domain optical coherence phase microscopy provides high resolution quantitative phase measurement. Using a common path Fourier domain optical coherence tomography system, this technique is capable of excellent phase stability of less than 1 milliradian and high imaging speed of up to several hundred KHz Aline rate. The limitation of 2π ambiguity restriction can be overcome by the use of a phase retrieval approach performed in spectral domain.
