Retrieval of original signals for superconducting quantum interference device operating in flux locked mode

doi:10.1088/1674-1056/24/4/047402

Abstract

We discuss a simple relation between the input and output signals of a superconducting quantum interference device magnetometer operating in flux locked mode in a cosine curve approximation. According to this relation, an original fast input signal can be easily retrieved from its distorted output response. This technique can be used in some areas such as sensitive and fast detection of magnetic or metallic grains in medicine and food security checking.
