Ultrasensitive Magnetometer
Visidyne has
recently developed and demonstrated an
improved
magnetic sensor under DARPA sponsorship. The Optical Faraday Magnetometer (OFM)
has sensitivities at the pico Tesla/Hz1/2 level that approaches the
performance of the cryogenic SQUID sensors but operates at room temperature.
The OFM solid-state sensor is small (the size of a pencil), low-weight,
requires little power and operates in the critical frequency domain from less
than 0.1 Hz to over 1 kHz. Patent is applied for improvements on the OFM.
Applications: Underwater surveillance,
IED detection, Security screening. Situational Awareness Surveillance of
target satellites.
