Self-referenced quantitative phase microscopy (SrQPM) is reported, wherein quantitative phase imaging is achieved through the interference of the sample wave with a reflected version of itself. The off-axis interference between the two beams generates a spatially modulated hologram that is analyzed to quantify the sample's amplitude and phase profile. SrQPM requires approximately one-half of the object field of view to be empty and optically flat, which serves as a reference for the other half of the field of view containing the sample.
