Abstract
This disclosure provides a method of controlling an electromagnetic field detector by causing a first phase shift to be applied to a second probe signal path so as to cause a variation in a change in intensity of combined first and second paths of a probe signal; obtaining data indicating a second phase shift to be applied to the second probe signal path so as to increase the change in intensity of the combined first and second paths of the probe signal, wherein the second phase shift is determinable from a variation in the change in intensity of the combined first and second paths of the probe signal caused by the first phase shift; and causing the second phase shift to be applied to the second probe signal path.
