MICRO FIBER OPTICAL SENSOR

摘要

A method is provided for producing an optical acoustic sensor. In one embodiment, a method comprises winding a single-mode optical sensor fiber around at least one mandrel. The optical acoustic sensor fiber can comprise a core region having a diameter of about 2 mum to about 8 mum and a cladding region having an outer diameter of about 8 mum to about 20 mum. The method can also comprise interconnecting the at least one mandrel into an optical acoustic sensor.
