title: Single-shot dual-illumination phase unwrapping using a single wavelength.
abstract: We propose a single-shot phase unwrapping technique using a single wavelength. In the proposed technique, an object is illuminated by two laser beams, which are emitted from the same laser, whose illumination angles and polarizations are different. Then two types of the object waves generated by the two beams are separately and simultaneously recorded by a polarization imaging camera. We conducted an experiment and a 2.5 mm height object, which was 9400 times height of the wavelength of the laser, was reconstructed without wrapping.
