lämpökamerasta

Lämpökamera, or thermal camera, is a device that detects and visualizes infrared radiation, which is emitted by all objects with a temperature above absolute zero. Unlike a conventional camera that captures visible light, a thermal camera creates an image based on the temperature differences of its surroundings. These images are often displayed in false colors, where different colors represent different temperature levels, allowing for easy identification of hotter and colder areas.

The core component of a thermal camera is a sensor that is sensitive to infrared wavelengths. When infrared radiation strikes the sensor, it generates an electrical signal that is then processed and translated into a visible thermal image. The resolution of a thermal camera refers to the number of pixels in its sensor, similar to standard digital cameras. Higher resolution generally leads to more detailed thermal images.

Thermal cameras have a wide range of applications. In building inspections, they are used to detect heat loss, identify insulation defects, and locate moisture problems. In industry, they monitor the temperature of machinery to prevent overheating and predict potential failures. For public safety and security, thermal cameras can be used for surveillance in low-light conditions or to detect intruders. They are also employed in fields like medicine for diagnostic purposes, in research for scientific analysis, and even in wildlife observation to track animals by their body heat. The ability to see heat without visible light makes thermal cameras a versatile tool for various professional and scientific tasks.
