Abstract
A particle detection system uses illumination incident at an angle to detect particles in a liquid such as water. By using illumination incident at an angle, the scattered light can be measured through a range of angles that are greater than the measured range of angles produced when the illumination is incident at a normal angle, when using the same detector. For example, the light can be measured through an angle that is twice that produced with illumination incident at a normal angle.
