We present an effective, fast, and straightforward phase aberration compensation method in digital holographic microscopy based on principal component analysis. The proposed method decomposes the phase map into a set of values of uncorrelated variables called principal components, and then extracts the aberration terms from the first principal component obtained. It is effective, fully automatic, and does not require any prior knowledge of the object and the setup. The great performance and limited computational complexity make our approach a very attractive and promising technique for compensating phase aberration in digital holography under time-critical environments.
我们提出了一种基于主成分分析的数字全息显微镜中有效的、快速的和直接的相位差补偿方法。该方法将相位图分解为一组不相关变量的值，称为主成分，然后从获得的第一主成分中提取像差项。它是有效的、全自动的，不需要任何关于物体和设置的先验知识。该方法性能优异，计算复杂度有限，使其成为在时间关键环境下补偿数字全息中相位差的一种非常有吸引力和有前途的技术。
