Abstract: We address the issue of how to properly treat, and in a more general setting,the concept of a weak value of a weak measurement in quantum mechanics. We showthat for this purpose, one must take in account the effects of the measuringprocess on the entire phase space of the measuring system. By using coherentstates, we go a step further than Jozsa in a recent paper, and we present anexample where the result of the measurement is symmetrical in the position andmomentum observables and seems to be much better suited for quantum opticalimplementation.
