Abstract
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.
