The brightness is often quantified using the RGB scale. But before getting started we must add a clarification: the term brightness is a subjective concept and therefore not used in optics to describe the units we will be discussing below, the term that is more commonly used by experts when discussing light is luminance. A light source or a light reflector is considered as a bright spot whereas a light absorbing surface is known as dark. Berlin Heidelberg: Springer-Verlag Theses. Brightness is a visual perception which enables the observer or the viewer to see an image as bright or dark. In oceanography, the microwave brightness temperature, as measured by satellites looking at the ocean surface, depends on salinity as well as on the temperature of the water. In particular, it is the temperature at which a black body would have to be in order to duplicate the observed intensity of a grey body object at a frequency ν In oceanography ( Learn how and when to remove this template message)īrightness temperature or radiance temperature is a measure of the intensity of electromagnetic energy coming from an source. Another way to express brightness is the amplitude of the wavelength where the intensity is greatest. It can be expressed as a total energy value, which is different for each of the curves in the Figure 2. ( August 2015) ( Learn how and when to remove this template message) Brightness, which is also referred to as brilliance, is an expression of the relative intensity of the energy output of a visible light source.
