What type of camera is used to measure heat energy emitted by objects?

The type of camera used to measure heat energy emitted by objects is an infrared camera. These cameras detect infrared radiation, which is a type of electromagnetic radiation emitted by all objects based on their temperature. When an object is heated, it emits more infrared radiation, and an infrared camera can capture this radiation and convert it into an image. This capability allows infrared cameras to visualize temperature differences between objects, making them invaluable in various applications, including thermal inspections, environmental monitoring, and search and rescue operations.

In contrast, digital cameras, HD cameras, and optical cameras primarily capture images in the visible light spectrum and do not have the ability to measure thermal radiation. While they can provide clear images of scenes as seen by the human eye, they cannot detect the heat emitted by objects, which is the fundamental function of an infrared camera. This distinction highlights the unique role of infrared technology in thermal imaging and temperature measurement.
