Digital holography is a well-accepted method for phase imaging. However, the phase of the object is always embedded in aberrations. Here, we present a digital holographic phase imaging with the aberrations fully compensated, including the high order aberrations. Instead of using pre-defined aberration models or 2D fitting, we used the simpler and more flexible 1D fitting. Although it is 1D fitting, data across the whole plane could be used. Theoretically, all types of aberrations can be compensated with this method. Experimental results show that the aberrations have been fully compensated and the pure object phase can be obtained for further studies.
数字全息术是一种广泛认可的相位成像方法。然而,物体的相位总是包含在像差之中。在此,我们提出一种能完全补偿像差(包括高阶像差)的数字全息相位成像方法。我们没有使用预定义的像差模型或二维拟合,而是采用了更简单且更灵活的一维拟合。尽管是一维拟合,但整个平面的数据都可以使用。从理论上讲,所有类型的像差都可以用这种方法进行补偿。实验结果表明,像差已得到充分补偿,并且可以获得纯净的物体相位以供进一步研究。
