Measurability of Electromagnetic Field: Model and Path Integral Methods
Horst von Borzeszkowski, Michael B. Mensky
abstract: The problem of the measurability of the electromagnetic field is investigated
1) in the framework of the abstract restricted-path-integral method, and 2) by
explicitly accounting the action of the field onto the meter and its back
reaction. The meaning of the previously obtained results as well as of the
classical results of Bohr and Rosenfeld are made clear. The
restricted-path-integral method with integration over field configurations is
shown to give an estimation on the measurability of the field by any device not
disturbing the measured field (in the process of measurement) more than by the
measurement error. Such method of measurement is necessary for the control of
the field in electronic devices.
