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.
我们提出了一种使用单一波长的单次相位解缠技术。在提出的技术中,物体被两个激光束照射,这两个激光束由同一激光器发出,其照明角度和偏振状态不同。然后,通过偏振成像相机分别并同时记录两个光束产生的两种类型的物体波。我们进行了实验,重建了一个 2.5mm 高的物体,其高度是激光波长的 9400 倍,没有缠绕。
