Abstract
The invention relates to a fiber-optic detector and concerns more particularly a detector capable of producing microbends in an optical fiber in response to the variation of a physical quantity or of an environmental parameter. The sensor of the invention consists of an optical fiber provide with a sheath which is covered by a layer exhibiting periodic discontinuities. The sheath and its covering react to the variation of the parameter to be detected in such a manner as to produce microbends of the same periodicity as that of the discontinuities.
