Biomedical Research Biophysics Optics Medical Imaging Physics laser speckle laser speckle contrast imaging flow imaging dynamic light scattering coherence imaging biomedical imaging blood flow measurement flow phantom This thesis presents data from a series of experiments that investigate the ability of laser speckle contrast imaging (LSCI) to sense changes in flow in turbid media. I first provide a theoretical overview and a description of the experimental approach used in this flow imaging technique. Experimental validation of the technique’s ability to sense induced changes in blood flow in the human forearm is demonstrated. Then, the technique’s sensitivity to buried flow in controlled optical phantoms is examined. It is shown that the buried depth and optical properties of the media surrounding flow impact the measured flow indices. Lastly, a study shows how the polarization state of the imaged light impacts the flow measurements as a function of the buried depth and rate of the flow. The results demonstrate that the measurements are dependent on the flow rates and optical properties of the sample as well as the imaging setup used to capture the speckle. 2018-07-30 English text Miami University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=miami153256524246362 http://rave.ohiolink.edu/etdc/view?acc_num=miami153256524246362 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
