What are the two missing words in this sentence? A __________ __________ camera detects infrared radiation and uses this information to create a picture.

The two missing words in the sentence are "thermal imaging."

So the complete sentence reads: "A thermal imaging camera detects infrared radiation and uses this information to create a picture."

Thermal imaging cameras are specialized devices that capture and visualize the infrared radiation emitted by objects. Unlike standard cameras that rely on visible light, thermal cameras visualize heat, making them invaluable in various fields such as security, search and rescue, building diagnostics, and medical applications. They operate by detecting the energy emitted from objects and converting it into a visual representation, often using color gradients to indicate different temperature ranges. This technology allows users to identify heat patterns that are otherwise invisible to the naked eye, helping in monitoring and diagnosing issues effectively.
