摘要	A coherent laser light flux is projected into a cell made of transparent quartz and light scattered from particles suspended in an antigen-antibody reaction liquid contained in the cell is detected by a photomultiplier by means of a collimator. An output electrical signal from the photomultiplier is sampled at different time instances and samplings are supplied to a fast Fourier transformer to derive a plurality of power spectrum densities of fluctuation in intensity of the scattered light. A plurality of power spectrum densities are averaged to generate a mean power spectrum density. An amount of antigen contained in the reaction liquid is measured in accordance with the mean power spectrum density.
其他摘要	将相干激光光束投射到由透明石英制成的单元中，并且通过光电倍增器通过准直器检测从悬浮在细胞中包含的抗原 - 抗体反应液中的颗粒散射的光。来自光电倍增器的输出电信号在不同的时刻被采样，并且采样被提供给快速傅里叶变换器，以导出散射光强度波动的多个功率谱密度。平均多个功率谱密度以产生平均功率谱密度。根据平均功率谱密度测量反应液中含有的抗原量。
