Geometrics Discusses MFAM Technology at SAGEEP in Denver

Mar 24, 2016 | Posted in Blog, News

Geometrics' engineer Easswar Balasubramaniam presented a talk entitled "Miniature Magnetometer Measurements Relevant to Deployment from Drones".

Easswar presented measurement results obtained with the first production version of our Micro-Fabricated Atomic Magnetometer (MFAM) in several tests of this novel total-field magnetometer. The MFAM measures the magnetic field at a rate of 1khz using a miniaturized Cesium-vapor sensor and our laboratory tests show it to be very sensitive, having a noise floor of 2 pT/SQRT. The results presented here were obtained from tests designed to evaluate the MFAM’s performance from extremely small platforms, including drones. These include the performance observed during:

1) A “swing test” of the device where the magnetic field measured at a point is recorded as a function of the changing orientation of the sensor;

2) High resolution measurements in noisy environments;

3) Introduction of MFAM based system designed for drone deployment

The results from the tests demonstrate the degree to which the MFAM is suitable for use on a moving platform. Other results provide notable examples of MFAM's application in situations where small sensor size, high sensitivity, high sample rate, and immunity to sensor-to-sensor interference are important.
