Search and Rescue
|
Humans and other living mammals usually radiate more heat than their
surroundings --especially in the cooler ambient air of the night.
Infrared cameras are particularly useful for detecting people and
animals during the darkness of night. In search and rescue operations,
infrared detectors are used to find people lost in thick foliage and
deep canyons, as well as in poor visibility conditions such as thick
fog, smoke, and heavy snow. Thermal infrared cameras can also be used
to find avalanche and earthquake victims buried under snow or debris.
Marine vessels can use infrared sensors to find marine disaster
survivors in the water during both day and evening searches. Infrared
technology plays an important role in searching for human survivors of
buildings that collapsed in earthquakes.

This image depicts a simulation of a person at sea in need of rescue.
The next time you are on a boat at sea, note how the sky and sea
conditions conspire to make it difficult to identify a potential victim,
especially if the wind produces choppy waves. An IR camera can easily
detect the heat of a person with relative ease.
