| 摘 要： | 为了进一步降低模间干涉传感器的运用复杂度及成本,采用1根单模光纤通过法兰管和耦合器直接连接多模光纤末端以截取干涉散斑的方式,构建了模间干涉传感器.通过Matlab仿真验证了设计的可行性,并按照设计频率进行振动实验,测试其在实际运用中的精确度及相应的强度.实验结果表明,该设计是一种简便、实用且高效的方案.

| Abstract: | To reduce the cost and simplify the system,in the paper,we use a single mode optical fiber to connect the multimode optical fiber to get a small area of speckles pattern.A emulator was designed to improve the feasibility of system with matlab.A experiment corresponding to frequency text are designed to test the system's performance and the result of vibration tests is given.A series of results indicate that the design is simpler and more efficient. |
