    • System and method for analyzing a sample for the presence of an analyte in a sample, the system comprising a sample holder for containing the sample; an excitation source in optical communication with the sample, wherein radiation from the excitation source is directed to the sample, and wherein the radiation induces a fluorescence signal; and at least one linear array comprising a proximal end disposed in proximity to the sample holder and an end port distal from the proximal end; a plurality of optical fibers extending from the proximal end to the end port and having a first end and a second end, wherein the first ends of the individual optical fibers are substantially coplanar and adjacent to one another, and wherein the second ends of the optical fibers form a non-linearly arranged bundle, and wherein the plurality of optical fibers transmits the fluorescent signal from the proximal end to the end port; and an end port assembly optically coupled to the end port, the end port assembly comprising a single photo-detector, wherein the photo-detector detects the fluorescent signal and converts the fluorescent signal into an electrical signal.
    • 用于分析样品中样品中存在分析物的系统和方法,所述系统包括用于容纳样品的样品保持器; 与样品光学通信的激发源,其中来自激发源的辐射被引导到样品,并且其中所述辐射诱导荧光信号; 以及至少一个线性阵列,其包括靠近所述样品保持器设置的近端和远离所述近端的端部端口; 多个光纤,从所述近端延伸到所述端口并且具有第一端和第二端,其中所述各个光纤的所述第一端基本上共面并且彼此相邻,并且其中所述光学器件的所述第二端 纤维形成非线性排列的束,并且其中所述多个光纤将所述荧光信号从所述近端传送到所述端口; 以及端接组件,其光耦合到所述端口,所述端口组件包括单个光检测器,其中所述光检测器检测所述荧光信号并将所述荧光信号转换为电信号。
