    • A system for use with a totally internally reflecting fiber-optic fluorescent assay apparatus (20) overcomes the problems of discriminating against internally generated fluorescence arising in polymeric fibers. The system includes a disc (50) that can be moved to alternately block and unblock a central colinear conical portion of an input cone of excitation radiation directed into an input end (28) of the fiber (30), thereby periodically varying the numerical aperture at the sensing region of the fiber surface. By analyzing the signal values received when that numerical aperture is relatively high with respect to those received when that numerical aperture is relatively low, one can determine what portion of the fluorescence at the sensing region (44) on the fiber surface as distinguished from various background fluorescence.
    • 与全内反射光纤荧光测定装置(20)一起使用的系统克服了在聚合物纤维中产生的内部产生的荧光的区别问题。 该系统包括盘(50),其可以被移动以交替地阻挡和解锁引导到光纤(30)的输入端(28)的激励辐射的输入锥的中心共弧锥形部分,从而周期性地改变数值孔径 在纤维表面的感测区域。 通过分析当该数值孔径相对于在该数值孔径相对较低时接收到的数值孔径相对较高时所接收到的信号值,可以确定纤维表面上的感测区域(44)的哪些部分与各种背景不同 荧光。
