摘要：

In this article, we report an implementation of distributed sensors that employ compact-grating-array structure, offering advantages of arbitrary dynamic range, high spatial resolution and simple interrogation by utilizing the established wavelength-division-multiplexing technique. The sensors have been demonstrated for measuring both linearly and non-linearly distributed strain with high spectral and spatial resolutions.
