Latest In Thermal Imaging
An infrared thermal camera detects and produces images of radiation in the infrared range. These images, called thermograms, display warm objects distinctly against cooler backgrounds. A thermal image camera, thus, allows a user to see temperature variations, resulting in thermography being extensively used by research laboratories and the military. In modern times, thermography is used to save the lives of both people and equipment.
Thermography is extensively used for:
Cancerous tumors require an ever-increasing supply of nutrients, therefore increasing circulation to their cells by holding blood vessels open. Frequently, this process increases regional surface temperatures of the breast. Medical imaging uses extremely sensitive infrared thermal cameras to detect and produce high-resolution diagnostic images of these temperature variations.
By revealing these temperature variations, infrared thermal cameras detect the earliest signs of breast cancer, thus expediting the treatment process.
Thermal imagers have proved invaluable in detecting lesions of the musculo-skeletal system of racehorses. Detection at an early stage prevents the development of more serious lesions.
Temperature variations in equipment are indicative of failing components. Using a thermal imager, such changes can be observed and maintenance can be scheduled to prevent equipment failure. A thermal image camera can also be used to keep in check high-speed bearings, fluid couplings, conveyor rollers, and storage tank internal build-up.
This process of observation to prevent failure is known as condition monitoring and forms a major component of preventive maintenance.
By perceiving thermal radiation without a source of illumination, thermal image cameras are excellent tools to provide human beings with night vision. In the darkest of nights, through fog, rain and smoke, thermal imagers product images of objects and people. This has led to infrared thermal cameras being widely used by firefighters and security forces.
Volcanologists monitor temperature changes indicative of upcoming volcanic activity using thermometers to observe changes in thermal properties of volcanic lakes and vents. Thermal imagers help them to monitor large, scarcely populated areas where maintenance of ground instruments is difficult and expensive.
Thus, by helping volcanologists to predict an eruption, thermography helps them to save many lives.
Infrared thermal cameras are invaluable tools for those in charge of building. Their many uses include:
Preventive maintenance of electrical systems
Thermography and insulation
Non-destructive inspection and testing
From being used in research facilities only, thermography has evolved into an important technique used in healthcare, commerce, real estate and science across the world. Equipping the user with the ability to observe temperature variations and see objects in the dark, infrared thermal cameras are certain to find applications in many more fields in the near future. This technology is certain to bring about a transformation, irrespective of the field it is introduced in.
