We present a single-shot dual-illumination phase-unwrapping technique using a single wavelength. Although dual-illumination phase unwrapping is a technique capable of high-accuracy three-dimensional (3D) shape measurement for even though a stepped-object, single-shot imaging was impossible because of the requirement of sequential recording of multiple holograms. In the presented technique, an object is illuminated by two laser beams simultaneously. The beams 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 simulated and experimented the presented technique, and a 3D shape of an object was reconstructed without wrapping. |
