Thermography, I see I see what you don't see and it's infrared

Thermography, also known as thermal imaging or infrared thermography, is a technology that uses infrared radiation to create images of temperature variations on the surface of objects or within a given environment. It is based on the principle that all objects emit infrared radiation (heat) in proportion to their temperature.

Here's how thermography works:

1. Infrared camera: A thermographic camera, or thermal camera, is used to capture the infrared radiation emitted by objects. These cameras are equipped with special sensors that can detect the heat signature of objects in the form of thermal patterns.

2. Temperature variation: Objects at different temperatures emit different levels of infrared radiation. Warmer objects emit more, while cooler objects emit less. Thermography is used to detect and visualize these temperature differences.

3. Image processing: The thermal camera captures infrared radiation and converts it into a visible image or video, with different colors or shades representing different temperatures. Generally, warmer areas appear as lighter colors (such as white or yellow), while cooler areas appear as darker colors (such as blue or black).

Thermography has a wide range of applications in various fields, including:

1. Building inspections: In construction and maintenance, thermography can identify areas of heat loss, insulation problems and electrical faults.

2. Medical imaging: In the medical field, thermography is used for breast cancer screenings and to identify areas of inflammation or abnormal blood flow.

3. Electrical inspections: Thermographic inspections of electrical systems can detect overheated components, which helps prevent electrical fires.

4. Mechanical inspections: It is used to monitor the temperature of mechanical equipment, such as bearings, to detect signs of wear.

5. Industrial processes: In manufacturing and industrial environments, thermography helps monitor process temperatures and detect defects.

6. Environmental and wildlife monitoring: Thermography is used to study and monitor animal behavior and health, and to monitor heat variations in the environment.

7. Security: Infrared cameras are used for surveillance and security to detect intruders, especially in low light conditions.

Thermography is a valuable tool for non-contact temperature measurement and anomaly detection, making it useful in a wide range of applications where temperature variations are critical for understanding and diagnosing problems.
