(Doc. ID 68025) We report a Koehler-illumination-based full-field, actively stabilized, low-coherence phase-shifting interfer-ometer, which is built on a white-light Michelson interferometer. By using a phase-stepping technique we can obtain full-field phase images of the sample. An actively stabilized phase-lock circuit is employed in the system to reduce phase noise. An application to human epithelial cells (HeLa cells) is achieved in our ex-periment. The advancement of this technique rests in its ability to take images of unstained biological samples quantitatively and on a nanometer scale.
