摘要：
The authors examine the changes in wavelength and attenuation of long period fibre gratings subjected to bends with curvatures from 0 to 4.4m(-1). The wavelength change with curvature is nonlinear, with a projected minimum detectable curvature change of 2 x 10(-3)m(-1). The magnitude of the bend-induced wavelength shift depends on the rotation of the cylindrical fibre relative to the bending plane.
