Abstract
An ensemble of spin-1/2 particles is observed repeatedly using Stern-Gerlac h devices with varying orientations. Synthesis of such noncommuting observa bles is analyzed using the maximum likelihood estimation as an example of q uantum-state reconstruction. Repeated incompatible observations represents a new generalized measurement. This idealized scheme will serve for analysi s of future experiments in neutron and quantum optics.
