BTheorySystem OverviewAs shown below, the SM-5 NAVMAG sensor consists of a sensor head withcable and sensor electronics.Figure B-1 SM-5 NAVMAG Sensor Head and ElectronicsThe sensor head has an electrodeless discharge lamp (containing cesiumvapor) and absorption cell. Electrical heaters bring the lamp and the cell tooptimum operating temperatures with control and driving circuits located inthe electronics console. Heating currents are supplied to the sensor headthrough the interconnecting cable.TheoryB-1SM-5 Manual - part # 872700 Revision 3

When operating, an RF oscillator in the electronics console provides RFpower to a lamp exciter in the sensor head and the radio frequency (RF) fieldproduces a corresponding resonant optical radiation (light).The light radiating from the cesium lamp is collimated by a lens. The lightpropagates in the direction of the sensor optical axis and passes through aninterference filter which selects only the cesium D1 spectral line. The light issubsequently polarized in a split, right/left hand circular polarizer before it isallowed to optically excite cesium vapor in the absorption cell.Theory of optical pumpingThe narrow bandwidth resonant light causes momentary alignment(polarization) of the atomic magnetic moments to the direction of theambient magnetic field. The resonant light "optically pumps" the cesiumatoms to a higher energy state. (Note that the polarizing light beam has to beoriented in the general direction of the ambient field to be effective.)Large numbers of cesium atoms can be polarized by optical pumping andthen induced to precess coherently in phase around the ambient field bymeans of a small magnetic field, H 1 . This small magnetic field is transverseto the ambient field and alternating at the Larmor frequency.The H 1 field is produced by a coil in the SM-5 NAVMAG. The coil iscoaxial with the sensor optical axis and wound around the absorption cell.Polarized resonant light perpendicular to the ambient magnetic field detectsthe precession. This light is alternately more or less absorbed, depending onthe instantaneous orientation of the polarization.In the SM-5 NAVMAG, this probing light is the perpendicular component ofthe resonant light beam. If the modulation of through-the-absorption-celltransmitted light is detected with the photosensitive detector, and theresulting Larmor signal is sufficiently amplified and phase-shifted beforebeing fed back to the H 1 coil, then a closed loop self-oscillating circuitresults.The resonance occurs at the Larmor frequency, which in weak fields, e.g. theEarth's magnetic field, is precisely linear with the field in which theabsorption cell is located. For the cesium 133 the proportionality constant(gyromagnetic constant) is 3.498577 Hz per nT.B-2SM-5 Manual - part # 872700 Revision 3

System OverviewAs indicated, different components of the same resonant light beam performtwo functions:• the component parallel to the ambient field performs the optical pumping• the perpendicular component detects the coherent precession.Therefore, no pumping is taking place if the light beam (the optical axis) isperpendicular to the ambient field (the equatorial orientation) andconsequently the sensor is not operating. Equally, no light modulation istaking place if the light beam is parallel with the ambient field (the polarorientation) and consequently the sensor is not operating.The second reason for the sensor not operating in the polar orientation is thatthe H 1 field, being parallel to the ambient field, can not induce precession ofthe magnetic polarization.Operating hemispheresThe plane perpendicular to the ambient field divides the sensor operatingzones into two hemispheres - northern and southern operating hemisphere. Inthe northern operating hemisphere the sensor light beam, which propagates inthe direction of the optical axis, Figure B-2, forms an angle from 0° to 90°with the direction of the ambient field. In this hemisphere, the phase shift ofthe Larmor signal amplifier required for the self-oscillation at the peak of theresonance is -90°.TheoryB-3SM-5 Manual - part # 872700 Revision 3

Figure B-2 Northern Operating HemisphereIn the southern operating hemisphere the light beam forms an angle from 90°to 180° with the ambient field direction, Figure B-3. There, the phase shift ofthe Larmor signal amplifier required for the self-oscillation at the peak ofresonance is +90°. Thus the phase change of 180° is required to make thesensor operational when the operating hemisphere is changed.B-4SM-5 Manual - part # 872700 Revision 3
