Thermal imaging

Definition

Thermal imaging is a technology that detects and measures infrared radiation emitted by objects, converting it into images that visualize temperature variations. This non-invasive method is widely used in various fields, including medicine, security, and building inspections, providing valuable insights based on thermal signatures.

5 Must Know Facts For Your Next Test

1. Thermal imaging cameras can detect temperature differences as small as 0.1 degrees Celsius, making them highly sensitive tools for identifying issues such as insulation problems or electrical failures.
2. In medicine, thermal imaging is used to detect conditions like inflammation or poor circulation by visualizing heat patterns in the body without physical contact.
3. Security systems utilize thermal imaging for surveillance and monitoring, as it can identify intruders even in complete darkness or adverse weather conditions.
4. Building inspectors use thermal imaging to locate heat leaks, moisture intrusion, or electrical faults, improving energy efficiency and safety in structures.
5. Thermal imaging can be combined with other technologies, such as machine learning algorithms, to enhance data analysis and provide predictive insights in various applications.
