Your fingerprint is actually 3D − research into holograms could improve forensic fingerprint analysis

Using fingerprints to catch criminals isn’t 100% accurate, but analyzing fingerprints in 3D, rather than 2D, could improve the process. ....

Digital Holography for 3D Display and Sensing

Digital holography is an interferometric imaging technique that uses light waves to image multi-dimensional information such as three-dimensional (3D) structures, quantitative phases, and dynamics. This technique revolutionizes the 3D visual representation of objects. ....

"Suppressing the Zero-Frequency Components in Single Quantitative Phase" by Jiale Long, Chuisong Meng et al.

In off-axis quantitative phase imaging, existing methods of suppressing the zero-frequency component (ZFC) always cause the loss of high-frequency phase information, thus degrading the accuracy of phase reconstruction. To overcome these problems, this paper proposes to preserve the high-frequency information by filtering the intrinsic mode function. In this method, empirical mode decomposition is employed to decompose the interferometric image into a series of intrinsic mode function (IMF) components from high to low frequencies. The decomposed low-frequency IMF components are processed by Gaussian high-pass filters for ZFC suppression, and the high-frequency IMF components and the filtered low-frequency IMF components are combined to obtain the reconstructed hologram. Hilbert transform is then performed on the reconstructed hologram to filter out the conjugate image, leaving only the original image. In order to verify the performance of our proposed method, the phase maps processed by ....
