This semiconductor wafer with visible image of Selçuk has a long way to go!	At the end of the way, it yields the thermal image of Selçuk.
LARGE FORMAT, LOW COST MWIR/LWIR DUAL BAND INFRARED SENSOR ARRAY Thermal images recorded with a Large Format MWIR/LWIR Voltage Tunable Dual Band QWIP FPA in the MWIR and LWIR modes. The FPA was fabricated in ouır laboratory including the molecular beam epitaxial growth of the multiquantum well structure. As to our knowledge, this is the first large format voltage tunable QWIP FPA reported. The fabrication approach allows the production of dual band sensors at the cost of single band FPAs. S. U.

HIGH QUANTUM EFFICIENCY, HIGH SPEED QWIP THERMAL IMAGING SENSOR The following thermal image is recorded with a 640x512 Quantum Well Infrared Photodetector (QWIP) Sensor Array with high quantum efficiency fabricated in our laboratory with an alternative semiconductor system (InP/InGaAs). The image is recorded with an integration time as low as 300 microseconds which is unusual for a QWIP FPA. The FPA facilitates successful thermal imaging even with such short integration times (allowing very high frame rates) due to exceptionally high quantum efficiency of the sensor. Y. Arslan,T. Colakoglu and C. Besikci, IEEE Journal of Quantum Electronics, vol. 49, pp. 186-195,2013.
