用于监测烟道中的微粒的装置和方法
摘要：
一种用于监测烟道中的颗粒的方法，该方法包括在烟道第一侧处产生朝向烟道的相对第二侧的光束。所述光束朝烟道的第一侧并穿过烟道中的颗粒而反射回。获取经颗粒散射的光的图像。所述图像是使用成像器而获取的，该成像器的方位和朝向方式使其具有包括不想要的散射光的视场。所述方法包括从图像中屏蔽不想要的散射光的步骤。
摘要（英）：

A method of monitoring particles in a stack comprises generating on a first side of the stack a beam of light directed towards a second, opposite, side of the stack. The beam is reflected back towards the first side of the stack and through the particles in the stack. An image is obtained of light scattered from the particles. The image is obtained using an imager positioned and oriented to have a field of view that includes unwanted scattered light. The method includes the step of blocking the unwanted scattered light from the image.
