Extended Short Wavelength Infrared FPA Technology: Status and Trends Beşikci, Cengiz (2018-02-02) This manuscript presents a survey of the extended short wavelength infrared (SWIR) FPA technologies with the emphasis on InxGa1-xAs imagers. We discuss the limitations of 2.5 mu m cut-off extended InxGa1-xAs photodetector ...
Theoretical assessment of electro-thermal imaging: A new technique for medical diagnosis Carlak, H. Feza; Gençer, Nevzat Güneri; Beşikci, Cengiz (Elsevier BV, 2016-05-01) Breast cancer is one of the most crucial cancer types. To improve the diagnosis performance, a hybrid system is proposed through simultaneous utilization of thermal and electrical impedance imaging methods. The innovation ...
Extended wavelength SWIR In GaAs focal plane array: Characteristics and limitations Arslan, Y.; Oguz, F.; Beşikci, Cengiz (2015-05-01) We present the characteristics of large format (640 x 512) short wavelength infrared (SWIR) InGaAs photodetector focal plane array (FPA) with similar to 2.65 mu m room temperature cut-off wavelength. The detector epilayers...
