    • In one embodiment, a drop detector includes a light source for illuminating drops passing through a drop zone and a light detector near the light source for detecting light scattered off the drops back toward the light source. In another embodiment, a drop detector includes a light source operable to emit a beam of light for illuminating drops passing through a drop zone and a light detector positioned near the light source to detect substantially only light scattered off the drops at a scatter angle θ in the range of 177° to 180°, where θ represents a direction of scattered light measured with respect to an axis of the light beam with θ=0° lying along the axis in a direction of travel of the light beam and θ=180° lying along the axis opposite the direction of travel of the light beam.
    • 在一个实施例中,液滴检测器包括用于照射通过液滴区的液滴的光源和靠近光源的光检测器,用于检测从液滴向光源散射的光。 在另一个实施例中,液滴检测器包括可操作地发射光束以照射通过液滴区的液滴的光源和位于光源附近的光检测器,以基本上只检测以散射角散射离开液滴的光; 在177°至180°的范围内,其中&thetas; 表示相对于具有沿着光束的光束的轴线测量的散射光的方向; = 0°,沿着光束的行进方向沿轴线倾斜; =沿着与行进方向相反的轴线180度 的光束。
