ATOMIC EMISSION SPECTROMETRY
... Instrument Design – Overview A spectrometer consists of three main parts: (1) an emission source, which produces the spectrum; (2) an optical system, which scatters the spectrum; and (3) a device to measure the emitted lines. The two major types of instrument for the analysis of emission spectra are ...

Localized - Current research interest: photon position
... In standard quantum mechanics a measurement is associated with an operator and collapse to one of its eigenvectors. For the position observable this requires a position operator and collapse to a localized state. The generalized theory of observables only requires a partition of the identity operato ...
