Ir brightness
WebInfrared (IR) sensing is a critical technology with wide-reaching applicability. It is used to detect and measure the IR radiation emitted by objects and environments without direct contact or visible light. Since heat is the most common source of IR radiation, it is often associated with thermography and thermal imaging. WebMar 26, 2016 · Sorted by: 1.

WebSep 7, 2024 · Metallic Reflection. When a light beam encounters a material, radiation can be absorbed or reflected by the surface. Metals are known for having high reflectivity, which explains their shiny appearance. Since the reflectance of light by metals is high their absorption is low because the sum of both must correspond to 100% of the incident light.
