    • In apparatus for detecting the emission of fluorescent radiation from a sample in response to excitation by two or more different radiation sources (145, 160) over the same time period, each radiation source (145, 160) is imprinted with a modulation regime which can then be separately detected in the emitted fluorescent radiation. For instance in techniques based on fluorescent resonant energy transfer (“FRET”), the drive current to two or more different LED sources (145, 160) may be frequency modulated, or pulse width modulated, according to different modulation regimes. Responses of the sample, for instance of different donor/acceptor probes contained in the sample, to each of the sources (145, 160) can then be separately detected by means of the different modulation regimes, even where the wavelengths or wavelength ranges of the responses are the same or overlapping.
    • 在用于响应于两个或更多个不同的辐射源(145,160)在相同时间段的激发来检测来自样品的荧光辐射的发射的装置中,每个辐射源(145,160)被印刷有调制方式,其可以 然后在发射的荧光辐射中单独检测。 例如,在基于荧光共振能量转移(“FRET”)的技术中,可以根据不同的调制方式对两个或更多个不同的LED源(145,160)的驱动电流进行频率调制或脉冲宽度调制。 然后可以通过不同的调制方式单独地检测样品(例如包含在样品中的不同施主/受体探针)到每个源(145,160)的响应,即使其中波长或波长范围 回应是相同或重叠的。
