【摘要】 本课题主要对反射式强度调制型光纤传感器进行数值模拟和仿真。通过模型化、数字化方法建立传感单元的数学模型，再利用矩阵进行空间和成像变换，最后实现模拟数据的可视化输出。模拟量的直观表达对使用和设计人员具有明显的辅助作用。 本文着重讨论了建立传感单元模型，模型数字化，四阶矩阵表述形式下的空间和成像变换，软件的编制方法等几方面关系到光纤传感CAD的具体理论问题。并对几种典型传感器的模拟曲线及其规律进行了分析和总结。 通过对其规律性进一步深入研究，初步找到了一种简便快捷的通用模拟算法，编制了具有一定实用性的光纤传感CAD软件，实现了对光纤传感器的数值模拟和仿真。更多还原

【Abstract】 Reflective intensity type modulating fiber optic sensors are simulated and emulated in this project. Firstly, digitizing model of sensing units is established by the methodology of mathematical model. Then, the visual data and simulation results are output by way of matrix space and image transforming. The visualization of fiber optic sensor simulation results is very useful and helpful for the user and designer.Based on the intensity type fiber optic modulation technique, the principle of fiber-optic sensor CAD is mainly discussed in detail. For example, the model of sensing units are founded, the model is digitized, the transformation of space and image is described by four-dimensional matrix, and software is designed. At the last, several typical practical fiber optic sensors’ modulating simulation curves and characteristics are analyzed and demonstrated.In summary, a kind of general and simple arithmetic have been founded through the in-depth investigation. The practical fiber optic sensors’ CAD software has been designed and finished. With the applying of the CAD software, all kinds of reflective intensity type fiber optic sensors’ design and simulation can be realized.更多还原
