摘　　要：自行设计并组装了一套以声光可调滤光片 ( AOTF)为波长选择系统的波长检测型表面等离子体子共振 ( SPR)传感器装置 ,介绍了 AOTF的特点和性能 .研究了传感器对乙醇、葡萄糖和蔗糖的响应特性 ,三者的线性范围分别为 5 %～ 60 %(体积分数 ) ,0 .0 2 8～ 0 .2 80和 0 .0 1 4～ 0 .1 4 0 mol/ L.并对葡萄糖和蔗糖的混合溶液进行了分析 .A surface plasmon resonance(SPR) experimental setup based on wavelength modulation using acousto optic tunable filter(AOTF) as the wavelength selector was described. The characteristic and performance of AOTF were introduced. Using the AOTF SPR sensor setup, alcohol, glucose and sucrose were determined. The linear ranges for the determination of alcohol, glucose and sucrose are 5%~60%(volume fraction), 0.028~0.280 mol/L, 0.014~0.140 mol/L, respectively. The mixture of glucose and sucrose was also analyz...
