Conduct a brief research on thermal scanners. What is its significance in the current scenario in a world affected by pandemic?
Answers
Answer:
Using infrared technology, thermal cameras detect radiating heat from a body - usually from the forehead - and then estimate core body temperature. These cameras are an extremely powerful tool, often deployed by fire fighters to track smouldering embers and police to search for out-of-sight suspects.
But they are not designed to be medical devices. So how useful are they in the current pandemic?
They can give a reasonable measure of skin temperature, to within half a degree - but that's not the same as body temperature.
"These devices, in general, are less accurate than medical device thermometers like those you stick in the ear," says Derek Hill, professor of medical imaging science from University College London.
