Thermal imaging works by detecting infrared radiation, which is a type of electromagnetic wave emitted by all objects based on their temperature. Essentially, the warmer an object is, the more infrared radiation it emits. Here's a quick breakdown:

1. Infrared Detection: Thermal cameras have sensors that can detect infrared radiation. Unlike regular cameras that capture visible light, these sensors pick up heat signatures.

2. Conversion to an Image: The thermal camera converts the detected infrared radiation into electronic signals. These signals are processed to create a thermal image, often displayed in color to show temperature variations. For instance, warmer areas may appear red, orange, or white, while cooler areas show as blue, purple, or black.

3. Application of Color Palettes: The final image uses a color palette to make it easier to identify temperature differences. This helps distinguish warm objects (like humans or animals) from cooler surroundings.

Thermal imaging is used in various fields—rescue operations, medical diagnostics, building inspections, and even wildlife tracking. It’s a fascinating technology that lets us “see” heat!
