Quantum Phase Angles and su(∞)
Journal of Modern Optics, 1991Abstract The polar decomposition of the su(2) algebra leads to unitary phase operators which do not close to an algebra with the number operator. It is shown that phase and number operators can be embedded into a larger su(2j + 1) algebra with trigonometric structure constants.

Power-system phase-angle measurements
Proceedings of the IEE Part A: Power Engineering, 1958The paper describes an instrument developed to record the phase variations between two 50c/s signals with a scale of ±12½°. The instrument was used during generator stability tests to record phase variations between the reference busbar voltage and a voltage at a remote point in the system undisturbed by the tests.

Phase Angle Measurement from Peak Areas (PAMPAS)
Journal of Magnetic Resonance, 2000A new method is described for accurate Phase Angle Measurement from Peak AreaS (PAMPAS) with the goal of facilitating automated phase correction of NMR spectra. PAMPAS measures phases of isolated NMR peaks by using Fourier analysis of a series of peak areas measured with systematically incremented phase shifts. The calculated phases of individual peaks
