    "abstract": "The relation between the restricted path integral approach to quantum\nmeasurement theory and the commonly accepted von Neumann wavefunction collapse\npostulate is presented. It is argued that in the limit of impulsive\nmeasurements the two approaches lead to the same predictions. The example of\nrepeated impulsive quantum measurements of position performed on a harmonic\noscillator is discussed in detail and the quantum nondemolition strategies are\nrecovered in both the approaches.",
