Wide-field reflection phase microscopy is highly desired for depth-resolved measurement of cellular structures without the need for raster scanning. We report a low coherence reflection phase microscope based on time-domain optical coherence tomography and off-axis interferometry. The setup uniquely provides the desired angular shift to the reference beam for off-axis interferometry while promising equal path length across the whole reference beam. We show subnanometer path-length sensitivity of our instrument and demonstrate high-speed imaging of membrane fluctuations in eukaryotic cells.
