Quantitative phase imaging using actively stabilized phase-shifting low-coherence interferometry
Optics letters, 2004•opg.optica.org
We describe a quantitative phase-imaging interferometer in which phase shifting and noise
cancellation are performed by an active feedback loop using a reference laser. Depth gating
via low-coherence light allows phase measurement from weakly reflecting biological
samples. We demonstrate phase images from a test structure and living cells.
