A large focus of this thesis was developing the experimental procedures involved in imaging VO2 during the heating process. In order to study light interactions between an induced dipole and a sample surface to collect various data on its topography, amplitude and phase. Data is collected using a near-eld microscope (s-SNOM) and analyzed using various software that, normalize, lter and display the data in false color image. Specically, research behind this thesis, focuses on the phase transition of Vanadium Dioxide (VO2) as it goes from an insulating to fully metallic phase. Using a wavelength of λ = 10:7μm to image the resonant behavior of the sample, the nucleation of VO2 was imaged as the temperature increased.
