local density of states
Local density of states (LDOS) is a physical quantity that describes the density of states, but space-resolved. In materials science, this term is useful when interpreting the data from an STM, since this method is capable of imaging electron densities of states with atomic resolution. According to crystal's structure, this quantity can be predicted by computational methods, as for example with density functional theory.
In optics and photonics the concept of local density of states refers to the states that can be occupied by a photon. For light it is usually measured by fluorescence methods, near-field scanning methods or by cathodoluminescence techniques.
