What is thermal imaging?

Thermal imaging is a technique used for detecting and measuring variations in heat energy and transforming that data into visible signals which can be recorded photographically. This technology is used to analyze the seaworthiness of a vessel, or to see alterations to a vessel that cannot be otherwise seen. The thermal imaging experts at AAC Marine Surveyors use this technology to identify problems that are potentially hazardous before it's too late, or to let a prospective buyer of a vessel know if there are any structural, electrical, or mechanical problems that can't be seen before they purchase the vessel. It can detect underlying abnormalities which cannot be detected otherwise.  more

Thermal imaging, also called thermography or thermal video, is the means by which humans may see in the infrared portion of the spectrum. Since every object gives off some amount of thermal radiation, thermal imaging is ideal for observing a scene in conditions of extreme darkness or when obscured by smoke, fog, rain, or snow. Some types of night vision use thermal imaging, and thermal imaging is considered the best form of night vision, as it can reveal objects in the blackest of nights. Thermal imaging is used widely in security, the military, navigation, surveillance, firefighting, industry, medicine, and science. The main tool for thermal imaging is the thermographic camera, which is similar in appearance and operation to a conventional camcorder. Thermal cameras pick up electromagnetic waves with a wavelength between roughly 0.9 and 14 micrometers. In contrast, electromagnetic waves in the visible portion of the spectrum have a wavelength between about 380 to 750 nanometers, ...  more

Thermography is the use of an infrared imaging and measurement camera to "see" and "measure" thermal energy emitted from an object (My dog Lucky was good enough to model for a test shot). Thermal, or infrared energy is light that is not visible because its wavelength is too long to be detected by the human eye; it's the part of the electromagnetic spectrum that we perceive as heat. Unlike visible light, in the infrared world everything with a temperature above absolute zero emits heat. Even very cold objects, like ice cubes, emit infrared. The higher the object's temperature, the greater the IR radiation emitted. Infrared allows us to see what our eyes cannot. Infrared thermography cameras produce images of invisible infrared or "heat" radiation and provide precise non-contact temperature measurement capabilities. Nearly everything gets hot before it fails, making infrared cameras extremely cost-effective, valuable diagnostic tools in many diverse applications. As industry strives to ...  more

Digital Infrared thermal imaging, or DITI, is a totally non-invasive, painless procedure with no radiation and no contact with the body. DITI is a clinical imaging technique that records the thermal patterns of your body. Your thermal images are used by your healthcare practitioner to help diagnose and monitor pain or pathology in any part of your body.  more

Infra-red radiation is emitted by every object above absolute zero, (-273C). The amount to which an object will emit infra-red radiation is partly governed by the temperature of the object. This infra-red radiation can be detected using a thermal imager which can then produce a pictorial representation of the object.

Infrared Thermography non-invasively locates, quantifies and documents electrical or mechanical thermal problems caused by faulty components, poor connections, corrosion, contamination, age, vibration, load imbalances, or lack of maintenance. What does thermal imaging look like? Visual Infrared GreyStones Certified Infrared Thermographer uses FLIR Systems ThermaCAM PM 695 Infrared Camera and software to simultaneously capture both Infrared Thermal and digital images, analyze and record the data, and document findings in a clear and concise report showing abnormalities and seriousness of detected problems.
