Abstract
Sensor shaped to have a frequency response that has less spectral fading than a sensor with a rectangular wrapping pattern, and methods for making such sensors, are disclosed. One such method includes selecting a wrapping pattern comprising multiple layers in which a top layer has a different length than a bottom layer and where the bottom layer is adjacent a mandrel. The method further includes wrapping optical fiber around the mandrel according to the wrapping pattern.
