Infrared emission is a research area that focuses on the emission of infrared radiation, which is a type of electromagnetic radiation with longer wavelengths than visible light. This area of research often involves studying the sources and properties of infrared emission, as well as its applications in various fields such as astronomy, remote sensing, and thermal imaging. Infrared emission can be emitted by objects that are at high temperatures, such as stars and planets, as well as by colder objects such as buildings and human bodies. Scientists and engineers in this field work to understand and harness the unique properties of infrared emission for a wide range of technological advancements.
