    • A pollen sensor and method for detecting pollen which discriminates pollen particles floating in air from other particles on a real time basis. The pollen sensor includes an illumination position for generating a light beam, a first receiver for measuring the intensity (I) or (Ip) of a light beam scattered by floating particles in a detection zone, a second receiver for measuring the intensity (Is) of a polarized light beam in a direction perpendicular to light illuminated by the light beam and means for measuring the degree of polarization of the particles for distinguishing pollen particles from other particles.
    • 一种用于检测花粉的花粉传感器和方法,其实时地鉴别浮在空气中的花粉颗粒与其他颗粒。 花粉传感器包括用于产生光束的照明位置,用于测量由检测区域中的浮动粒子散射的光束的强度(I)或(Ip)的第一接收器,用于测量强度(Is)的第二接收器, 的偏振光束在垂直于由光束照射的光的方向上的偏振光束,以及用于测量用于区分花粉粒子与其他粒子的粒子的偏振度的装置。
