Agricultural Crop Monitoring with Computer Vision
… cameras sensitive to visual (430-650~nm), near infrared (NIR,750-900~nm), shortwave infrared (SWIR,950-1700~nm), and longwave infrared (LWIR,7500-16000~nm) light. Three areas are considered in the study: image segmentation, multispectral image registration, and the feature tracking of a stressed …

Engineered quantum dots for infrared photodetectors
Quantum Dot Infrared Photodetector (QDIP) Focal Plane Arrays (FPAs) have been proposed as an alternative technology for the 3rd generation FPAs. QDIPs are emerging as a competitive technology for infrared detection and imaging especially in the midwave infrared (MWIR) and longwave infrared (LWIR) …

Low temperature heterogeneous integration of germanium on silicon
… range (1.3-1.55 µm), its transparency in the mid-longwave infrared (mid-LWIR) range, and its ease of integration on a Si backbone make it a perfect candidate for photodetectors (PDs) for Telecom optical interconnects and waveguides for mid-LWIR optical sensors. However, optical interconnects are …

Unipolar barrier strained layer superlattice infrared photodiodes : physics and barrier engineering
… (T2SL) is an emerging technology for infrared detection. They are being seen as a threat to 50 years old incumbent technology based on Mercury-Cadmium-Telluride (MCT) system. T2SL have been theoretically predicted to outperform MCTs. This dissertation has been aimed at improving the …

Radiation-induced condensational growth of cloud-sized mist droplets
… including the effects of both shortwave and longwave (infrared) thermal radiation. The potential importance of infrared thermal radiation on cloud droplet evolution, particularly at cloud top, has been known in theory for over a century. Yet, despite Osborne Reynolds’ pioneering 1877 …

An investigation into the complementary capabilities of X-ray computed tomography and hyperspectral imaging of drill core in geometallurgy
… (such as serpentine-olivine in visible-shortwave infrared and plagioclase-chlorite in the longwave infrared) and unclassified minerals in the core. The resultant mineral assemblage was comparable to QEMSCAN and QXRD in terms of minerals present with generally similar abundances. However, useful …
