Medical infrared imaging – differentiating facts from fiction, and the impact of high precision quantum well infrared photodetector camera systems, and other factors, in its reemergence

Thermal imaging of a vein of the forearm: Analysis and thermal modelling

“…Infrared thermography is a non-destructive technique which delivers temperature images of the human body, integrating the thermal sources over a few millimetres in depth. Until now, biomedical applications of infrared thermography have given rise to very few clinical trials [7,8]. Usually, the diagnosis of anomalies by thermal imaging is only based on the observation of comparative temperature asymmetries between normal and abnormal sites, sometimes in conjunction with other imaging techniques [9][10][11][12].…”

ABSORPTION COEFFICIENT IN A MQW INTERSUBBAND PHOTODETECTOR WITH NON-UNIFORM DOPING DENSITY & LAYER DISTRIBUTION

“…Researchers have utilized this novel feature to design intraband or intersubband photodetectors using multiple quantum well structures for color spectra detection that overcome the limitation of monochromatic wavelength absorption by traditional bulk interband photodetectors [4][5][6]. In recent days Quantum Well Infrared Photodetectors (QWIPs) are widely used for short, mid, long and very-long wavelength infrared detection, thermal imaging, medical imaging and many other real life applications [7][8][9]. The impact of number of wells, doping density, applied bias and position of quasi-bound states on the operating wavelength and other performance parameters of the intersubband QWIPs have been reported by the researchers for multifarious applications [10][11][12][13].…”

Thermal conductivity of porous silica films using modified polydimethylsiloxane and polyethyleneglycol as templates by sol–gel process

“…Infrared (IR) detectors have recently decreased in size but improved in performance and availability [1,2], as well as realized a wide variety of applications including medical diagnosis [3], environmental monitoring [4], surveillance [5], firefighting [6], industrial inspection [7], energy conservation [8], and automotive night vision [9]. IR detectors include photon and thermal detectors.…”
