研究目的
To design and analyze an optical fiber biological sensor for measuring and monitoring the glucose ratio in blood samples.
研究成果
The study demonstrated that as the refractive index of serum samples increases, the parameters of refractive index step and output power decrease linearly. This method can be used for assessing serum glucose levels without the need for reagents.
研究不足
The method requires a large sample size to set a standard table for serum glucose level measurement and does not use any reagents.
1：Experimental Design and Method Selection:
The sensor was designed using a Mach-Zehnder interferometer with multimode fibers, simulated using Optisystem software.
2：Sample Selection and Data Sources:
Serum samples with different glucose concentrations were used, with their refractive indices measured using an Abbc-refractometer.
3：List of Experimental Equipment and Materials:
Continuous wave laser, Mach-Zehnder modulator, optical spectrum analyzer, and multimode optical fibers.
4：Experimental Procedures and Operational Workflow:
The cladding of the fibers was stripped and replaced with serum samples. The optical power and mode were analyzed for each sample.
5：Data Analysis Methods:
The refractive index and output power were analyzed to determine the relationship with glucose concentration.
