    • A method of measuring a resonant wavelength of a resonant waveguide (RWG) biosensor in an array of RWG biosensors supported by a microplate in a label-independent optical reader is disclosed. An exemplary method includes scanning a light spot over the RWG biosensor to obtain a plurality of spectra from both a central portion and at least one edge portion of the RWG biosensor. The method includes calculating a weighted-average spectrum for the biosensor by averaging the plurality of spectra while applying greater weight to the central portion than to the at least one edge portion. The method includes determining the resonant wavelength from the weighted-average spectrum. The resulting resonant wavelength measurement has substantially reduced noise and provides improved performance for label-independent scanning optical reader systems that use scanned optical beams.
    • 公开了一种在标签无关的光学读取器中测量由微孔板支持的RWG生物传感器阵列中的谐振波导(RWG)生物传感器的谐振波长的方法。 一种示例性方法包括在RWG生物传感器上扫描光点以从RWG生物传感器的中心部分和至少一个边缘部分获得多个光谱。 该方法包括通过对多个光谱进行平均来计算生物传感器的加权平均光谱,同时对中心部分施加更大的权重而不是至少一个边缘部分。 该方法包括从加权平均光谱确定谐振波长。 所得到的谐振波长测量具有显着降低的噪声,并且为使用扫描光束的标签无关扫描光学读取器系统提供改进的性能。
