Fiber Optic Magnetic Sensor Research.

The direction of technological advance which will lead to the development of a deployable fiber-optic magnetic sensor has been brought into closer focus as a result of studies conducted under this contract. It is useful to categorize our work as comprised of the following constituent efforts: (a) Componentry and configuration of optical sensors in general; (b) Transductive componentry whereby a magnetic field effects a measurable change in a sensor system. This includes characterization and optimization of magnetostrictive materials; (c) Configuration of a magneto-sensitive material for specialized applications (tailoring of orientational characteristics, for example) for measurement of total field, vector field, field gradient, etc.; (d) Data acquisition techniques suited to the chosen transduction mechanism and the optical configuration and sensitivity/spectral-response requirements of the application.
