Download or read book Methods of Digital Holography written by Leonid Yaroslavskii and published by Springer. This book was released on 2013-10-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital holography is the analysis and synthesis of wavefronts by means of digital computers. Here "analysis" means the construction of images of objects and the measurement of their physical characteristics by recording and measur ing the wavefronts scattered by these objects. The "synthesis" is the reconstruc tion of a wavefront of an object which is specified numerically. Problems involving the analysis and synthesis of wave fronts arise frequently in modem science and engineering. These are the problems encountered in the use of electromagnetic and sound waves to peer into the interior of various objects, the problems of the visual display of information in general, and the problems of measuring the characteristics of radiating systems, devising optical apparatus for signal processing, and developing hybrid electrooptic computer systems. Solutions are being sought for these problems through research in holography. The use of digital computers to analyze and synthesize wavefronts is an alternative to the analog methods, which include the methods of physical holography. The digital approach potentially has the advantages which are inherent in the digital technique for signal processing: the processing is highly accurate and absolutely reproducible; the characteristics of the processing or the processing algorithm itself can be changed in a simple way; complicated nonlinear and logic conversions can be carried out; the results are accessible; and it is easy to modify the process at any stage. Digital methods are particularly suitable where quantitative results are required.

Download or read book Holographic Microscopy of Phase Microscopic Objects written by Tatyana Tishko and published by World Scientific. This book was released on 2011 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a clear and comprehensive review of the current status of three-dimensional (3D) digital holographic imaging of phase microscopic objects, with insightful discussions on the positive and negative features of classical, electronic and holographic microscopy. The technical details and results of the restoration of the 3D shapes of red blood cells, bacteria, yeasts, thin films and other micro-objects are presented. The physical background of the method was substantiated by the authors in 1989 and in 1998, the very first digital holographic interference microscope was developed. Clear evidence of the pathological flattened shape of the erythrocytes relevant to different pathologies is given by detailed measurements on the 3D images. Based on the model of the erythrocyte as a liquid-filled, charged, and viscoelastic shell reinforced by skeleton, numerical computations of the equilibrium shapes of human erythrocytes are made, and the results are analyzed and compared to the 3D visualization data.
Download or read book Holoscopy written by Dierck Hillmann and published by Springer. This book was released on 2014-07-08 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Holoscopy is a new tomographic imaging modality that combines techniques of digital holography with Fourier-domain optical coherence tomography (FD-OCT). Dierck Hillmann gives a theoretical introduction to the mathematics and physics of holoscopy and develops an efficient numerical reconstruction procedure. Compared to FD-OCT, holoscopy provides unique advantages by enabling tomographic imaging without a limited depth of focus, but results in an increased numerical cost for reconstruction. In further chapters, the author introduces techniques for FD-OCT that are relevant to holoscopy as well. He demonstrates and compares numerical reconstruction methods for FD-OCT and shows how motion and dispersion artifacts in FD-OCT can be numerically compensated.
