Acoustic Coherence Imaging Through the Atmosphere
"The imaging of acoustic ""scenes"" through the atmosphere is a subject with little treatment in the literature. This thesis strives to set the state of the art in this field by presenting imaging methods and their performance in the turbulent atmosphere. Both narrowband interferometry and wideband …

MEG coherence imaging in dyslexia: Activation of working memory pathways
… structural, and functional brain imaging studies that are the foundations of our understanding of dyslexia and 2) investigate the pattern of activation and functional connectivity of neuronal networks critical in working memory in dyslexics by means of magnetoenchephalographic …

Coherence imaging technologies for the measurement of tissue and cell biomechanics
… at the intersection of biomechanics and optical imaging, and focuses on optical elastography, an optical sensing and imaging technique used to measure biomechanical properties at the tissue and cell levels. Optical coherence elastography, multiphoton elastography, and magnetomotive microscopy are …

System Design And Optimization Of Optical Coherence Tomography
Optical coherence imaging, including tomography (OCT) and microscopy (OCM), has been a growing research field in biomedical optical imaging in the last decade. In this imaging modality, a broadband light source, thus of short temporal coherence length, is used to perform imaging via interferometry. …

Spectral domain interferometry: A high-sensitivity, high-speed approach to quantitative phase imaging
… applications. Thus, quantitative phase imaging becomes an important technique to measure the phase variations due to the difference of refractive index and geometric thickness of various structures and materials within the biomedical specimens. In this thesis, a spectral modulation …

Phase derivative microscopy of biological cells and tissues
… microscopy, which is a traditional method of imaging the derivative of the phase, PDM shows higher stability because there are no mechanically moving parts involved in the operation. More importantly, unlike DIC, PDM does not use polarizing optics and, thus, it is applicable to birefringent …

Dynamic holography in semiconductors and biomedical optics
… drivers such as 3D printing and remote imaging for big data applications. Holography is a natural approach to recording and displaying three-dimensional information because it uses phase-sensitive interferometry to record interference patterns when a reference beam encounters coherent …
