Abstract
Some recent ideas concerning Pancharatnam's prescription of relative phase between quantal states are delineated. Generalisations to mixed states and entangled two-photon states are discussed. An experimental procedure to test the geometric phase as a Pancharatnam relative phase is described. We further put forward a spatial split-beam dual to Pancharatnam's relative phase.
