Schultze, Volkmar Schillig, Bastian IJsselsteijn, Rob Scholtes, Theo Woetzel, Stefan Stolz, Ronny 2017-03-10 We present an optically pumped magnetometer working in a new operational mode— the light-shift dispersed Mz (LSD-Mz) mode. It is realized combining various features; (1) high power off-resonant optical pumping; (2) Mz configuration, where pumping light and magnetic field of interest are oriented parallel to each other; (3) use of small alkali metal vapor cells of identical properties in integrated array structures, where two such cells are pumped by circularly polarized light of opposite helicity; and (4) subtraction of the Mz signals of these two cells. The LSD-Mz magnetometer’s performance depends on the inherent and very complex interplay of input parameters. In order to find the configuration of optimal magnetometer resolution, a sensitivity analysis of the input parameters by means of Latin Hypercube Sampling was carried out. The resulting datasets of the multi-dimensional parameter space exploration were assessed by a subsequent physically reasonable interpretation. Finally, the best shot-noise limited magnetic field resolution was determined within that parameter space. As the result, using two 50 mm3 integrated vapor cells a magnetic field resolution below 10 fT/√Hz at Earth’s magnetic field strength is possible. application/pdf https://folia.unifr.ch/global/documents/305581 https://folia.unifr.ch/documents/305581/files/sch_opm.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.3390/s17030561 info:eu-repo/semantics/openAccess License undefined Sensors. - 2017, vol. 17, no. 3, p. 561 magnetometer optically pumped magnetometer light shift Mz magnetic-field resolution Latin Hypercube Sampling Downhill simplex info:eu-repo/classification/udc/53 An optically pumped magnetometer working in the light-shift dispersed Mz mode http://purl.org/coar/resource_type/c_6501
