Annealing studies of detector materials for uncooled thermal imaging
Uncooled thermal imaging is a key technology for military applications. The sensors used are thermal detectors which respond to changes in temperature resulting from absorption of infrared radiation, generally in the 8-14µm waveband. In the UK these have been principally based on the pyroelectric …

Thermal imaging of quenched microstructural evolution in steel alloys
A method was devised for quenching undercooled samples of Fe-12Cr-16Ni. The samples were levitated in a magnetic field as a way of containerless processing. They were dropped onto a nucleation trigger and then into a quenching bath. This process was successful in producing quenched samples , but …

Communication-theoretic Approach for Skin Cancer Detection using Dynamic Thermal Imaging
… studies have evaluated the use of infrared imaging to diagnose skin cancer. Here we use dynamic thermal imaging (DTI) to demonstrate a rapid, accurate and non-invasive imaging and processing technique to diagnose melanoma and non-melanoma skin cancer lesions. In DTI, the suspicious lesion is …

Development of a display screen correlation metric for thermal imaging cameras
Thermal imaging cameras detect infrared radiation to semi-quantitatively determine the thermal profile of the surroundings. Previously, no standard performance measurements have been established for thermal imaging cameras applications such as search and rescue and firefighting. The spatial …

The role of infrared thermal imaging in the assessment of chronic midportion Achilles tendinopathy
Infrared thermal imaging cameras (IRC) are non-contact devices that allow the capture of radiation presented in the form of colour-coded images, therefore they may provide an effective method of assessment for chronic midportion Achilles tendinopathy. Some of the features of the condition point …
