# Dispersion on a sphere

@article{Fisher1953DispersionOA, title={Dispersion on a sphere}, author={Rory A. Fisher}, journal={Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences}, year={1953}, volume={217}, pages={295 - 305} }

Any topological framework requires the development of a theory of errors of characteristic and appropriate mathematical form. The paper develops a form of theory which appears to be appropriate to measurements of position on a sphere. The primary problems of estimation as applied to the true direction, and the precision of observations, are discussed in the subcases which arise. The simultaneous distribution of the amplitude and direction of the vector sum of a number of random unit vectors of…

The random nature of light emitters requires that the theory to study polarization must adopt a statistical approach, and here the polarization dynamics on the Poincaré sphere of random light sources is described through the von Mises-Fisher distribution.
