Using fingerprints to catch criminals isn’t 100% accurate, but analyzing fingerprints in 3D, rather than 2D, could improve the process.
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.
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 Gau...
The stunning experiment, which reconstructs the properties of entangled photons from a 2D interference pattern, could be used to design faster quantum computers.
