Ptychography for Nonlinear Optical Microscopy Norris, Evan Ramunno, Lora Nonlinear Optical Imaging Ptychography In this thesis I will introduce a novel nonlinear optical microscopy method to address some of the shortcomings in the current nonlinear optical microscopy literature and offer a supplement to traditional fluorescent microscopy for label free optical biomedical imaging. In order to demonstrate this method I describe a method for the generation of a numerical sample of collagen fibrils, produce a set of numerical diffraction measurements. I introduce a novel Ptychography model for the simultaneous reconstruction of the components of the nonlinear optical susceptibility tensor and demonstrate the results of this model using numerically generated measurements from a numerical collagen sample. I additionally use the recovered information from Ptychography to retrieve new information about the structure of a sample. 2021-09-08T20:56:10Z 2021-09-08T20:56:10Z 2021-09-08 Thesis http://hdl.handle.net/10393/42648 http://dx.doi.org/10.20381/ruor-26868 en application/pdf Université d'Ottawa / University of Ottawa
