摘要

为提高复合式光纤法布里-珀罗传感器的相关解调分辨率,提出了一种基于新型复合式光楔的非扫描相关解调系统。根据所解调复合式光纤法布里-珀罗传感器各腔体光学厚度变化范围,沿线阵CCD像素点排布方向,设计了分段式不同倾角和厚度范围的空气间隙式光楔结构,实现了多个法布里-珀罗腔腔长的复合同步解调。针对基底腔和空气腔腔长分别为600 μm和80 μm的复合式光纤法布里-珀罗传感器,设计了复合式光楔,仿真并分析了其解调性能。结果表明,采用基于复合式光楔的非扫描相关解调方案,可以实现光学厚度差异较大的多法布里-珀罗腔构成的复合式光纤法布里-珀罗传感器的同步高精度解调,腔长解调分辨率优于单光楔解调。

Abstract

A new type of non-scanning correlation demodulation system based on a new compound optical wedge structure is introduced in order to improve the correlation demodulation resolution of compound fiber Fabry-Perot (FP) sensors. Based on the desired demodulation range of the optical thickness of each cavity of the compound fiber FP sensors along the pixel arrangement direction of the linear array CCD, an air-gap optical wedge structure having different tilt angles and thickness ranges is designed and adopted to achieve the compound synchronous demodulation of multiple FP cavity lengths. The demodulation performance of the designed compound optical wedge structure is simulated and analyzed for compound fiber FP sensors having basal and air-cavity lengths of 600 μm and 80 μm, respectively. Simulation results show that such sensors with multiple FP cavities and different optical thicknesses are demodulated synchronously and accurately using the proposed non-scanning correlation demodulation system based on the compound optical wedge structure. The demodulation resolution for a compound fiber FP sensor can be better than that of a single optical wedge. This conclusion is particularly true for a compound fiber FP sensors comprising cavities with large cavity length differences.
