Phase aberration compensation in digital holographic microscopy based on principal component analysis

Abstract: 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 computation… Show more

“…So the phase of object can be obtained by a numerical propagation of the complex intensity, which is compensated by eliminating the second-order aberration. Due to the tilt function, the three parts in the frequency domain can be easily separated [11]. So we can get the complex function responding to 1 ( , ) f   in the form of …”

“…Quantitative phase imaging (QPI) is an effective approach to recover the phase of unlabeled biological samples without phototoxicity or photobleaching as in fluorescence microscopy. 3 Conventional off-axis digital holographic microscopy (DHM) [4][5][6] measures the total phase delay of sample by the spatial modulation of heterogeneous refractive index within the sample. And some other interference approaches utilizing the common path geometries and white light source have been presented to improve imaging resolution and quality of quantitative phase result [7][8][9] as well.…”

“…Recently, in the field of digital holography, Zuo et al [21] employed the principal component analysis (PCA) to compensate the phase aberration. Here, we introduce the PCA into our work aiming at removing the carrier in FTP for the divergent illumination measuring system.…”
