摘要：

A fiber optical based on a miniature fiber collimator Fabry-Perot Interferometer (FPI) is demonstrated for bend measurements. The device consists of a quarter-pitch graded index fiber (GIF) spliced with a section of silica tube, which is interposed between single mode fibers. The divergence angle of the included miniature fiber collimator was 0.058 rad. In comparison, the divergence angle without the collimator was 0.130 rad. The sensitivity of a miniature fiber collimator FPI is found to enhance to -1.552 dB/degree over the applied angle range.
