Journal ArticleDOI
Encryption of digital hologram of 3-D object by virtual optics.
TL;DR: In this technique the digital hologram is encrypted by attaching a computer-generated random phase key to it and then forcing them to Fresnel propagate to an arbitrary plane with an illuminating plane wave of a given wavelength.
Journal ArticleDOI
Automated quantitative analysis of 3D morphology and mean corpuscular hemoglobin in human red blood cells stored in different periods
TL;DR: Modifications of the 3D morphology and MCH in RBCs induced by the period of storage time are investigated for the purpose of classification of R BCs with different periods of storage by using off-axis digital holographic microscopy.
Journal ArticleDOI
Hermite-Gaussian and Laguerre-Gaussian beams beyond the paraxial approximation
Hyo-Chang Kim,Yeon H. Lee +1 more
TL;DR: In this paper, the exact electric field vectors of the higher-order Hermite Gaussian and Laguerre Gaussian beams were derived from the transverse component of the electric field given at the z = 0 plane by use of the angular spectrum method and electric field divergence theorem.
Journal ArticleDOI
CEP-stable, sub-6 fs, 300-kHz OPCPA system with more than 15 W of average power.
Stephan Prinz,Matthias Haefner,Catherine Y. Teisset,Robert Bessing,Knut Michel,Yeon H. Lee,Xiao Tao Geng,Seungchul Kim,Dong Eon Kim,Thomas Metzger,Marcel Schultze +10 more
TL;DR: A CEP-stable OPCPA system reaching multi-GW peak powers at 300 kHz repetition rate and by implementing an additional pump-seed-synchronization, the output parameters are stabilized over hours with power fluctuations of less than 1.5%.
Journal ArticleDOI
Optimal watermarking of digital hologram of 3-D object.
Hyun You Kim,Yeon H. Lee +1 more
TL;DR: It is shown in the experiment that the digital hologram watermarked with the optimum weighting factor produces the least errors in the reconstructed 3-D host object and the decoded watermark even in the presence of an occlusion attack.
