摘　　要：光电式多波长传感器(Photoelectric Multiple-wavelength Sensor,PMWS)是一种新型传感器。将PMWS运用于液滴分析技术中构成多波长液滴分析仪,可获得有关液滴体积及基于不同波长的光信号随液滴生长变化的信息,从而得到包含被测液体特性信息的液滴指纹图。利用该传感器,还可采用CCD摄像装置实时获取液滴的轮廓信息,而多波长光源的运用又可以更深入地了解液体的光学特性。The photoelectric multiple-wavelength sensor（PMWS） is a new developed sensor that used in the liquid signature analysis technology. With PMWS, the varying light intensity signal passing through the liquid drop and the instantaneous drop volume signal can be achieved simultaneously, and consequently the liquid drop trace integrating the two kinds of information of liquid is available. PMWS provided position for CCD camera to capture the profile information of the liquid drop, and the multiple-wavelength light source made it possible to gain characteristic information of the liquid drop based on different wavelength.
