The development of optically pumped magnetometer systems and their applications in Australia: Part 2

When the first optically pumped magnetometer was developed it was immediately recognised that if the very fast measurement rate attribute could be exploited through automatic recording and the provision of an odometer system for automatically determining the location of each measurement, magnetic mapping would be revolutionised. With these combined developments instead of acquiring magnetic measurements at 20 m intervals or even greater, as was previously the standard, it became practical to record magnetic profiles at sub-metre sample intervals. This could now be done while travelling faster than an operator could walk, and even up to 40 kph with a vehicle-borne platform.
