Method and apparatus for determining a relaxation time dependent parameter related to a system

摘要

A method for determining at least one parameter related to a system is disclosed, wherein the at least one parameter depends on at least one relaxation time of the system. The system is excited by a first series of electromagnetic excitation pulses, exhibiting a first defined time gap between consecutive excitation pulses. The response of the system to the first series of excitation pulses is integrated uninterruptedly over time, thus generating a first response signal. Likewise, by uninterrupted integration over time of at least one second response of the system, a second response-signal is generated. The at least one parameter is determined taking into account the first response-signal and the at least one second response-signal.
