Spectral and spatial control of broadband light using wavefront shaping
Yolalmaz, Alim; Yüce, Emre; Yerci, Selçuk; Department of Micro and Nanotechnology (2022-2-9)
Spectral and spatial control of light strongly influences central fields such as solar energy, spectroscopy, holography, and imaging. Enhanced control of propagation, diffraction, scattering, and interference of light using micro-and nano-structures leads to superior performance in these fields. This thesis presents light control in spectral and spatial domains using wavefront control for solar energy, spectroscopy, holography, and imaging applications. Spectral splitting of the sunlight using diffractive o...
Spectral correction-based method for interharmonics analysis of power signals with fundamental frequency deviation
Salor, Oezguel (Elsevier BV, 2009-07-01)
In this paper, a spectral correction-based algorithm for interharmonic computation is proposed for especially highly fluctuating fundamental frequency cases in the power system. It has been observed and reported that fluctuating demands of some loads such as arc furnaces, or disturbances and subsequent system transients make the fundamental frequency of the power system deviate and this causes non-existing interharmonics to appear in the spectrum due to grid-effect when a standard window length is used for ...
Spectral and statistical analyses of experimental radar clutter data
Kahyaoğlu, Nazlı Deniz; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2010)
The performance of radar detection and imaging systems strongly depends on the characteristics of radar clutter. In order to improve the radar signal processing algorithms, successful analysis and modeling of radar clutter are required. For a successful model of radar clutter, both the spectral and statistical characteristics of the clutter should be revealed. Within the scope of this study, an experimental radar data acquisition system is established to analyze radar clutter. The hardware and the data proc...
Spectral graph based approach for analysis of 3D lidar point clouds
Bayram, Eda; Alatan, Abdullah Aydın; Vural, Elif; Department of Electrical and Electronics Engineering (2017)
Airborne Laser Scanning is a well-known remote sensing technology, which provides quite dense and highly accurate, yet unorganized, point cloud descriptions of the earth surface. However, processing of such a 3D point cloud is quite challenging due to its irregular structure and 3D geometry. In this thesis,two novel approaches for the analysis of unorganized 3D point cloud data are proposed, specifically the ones that are generated by the airborne mounted LIDAR sensor. These methods rely on the spectral grap...
