Abstract: A method has been derived that can image radiation scattered from particles in the near field to the focal plane of an imaging sensor, using only two system level parameters. The parameters needed are the effective focal length and back focal length of the imaging system. The inherent advantages of this method are that imaging of scattered radiation and near field objects can be modelled with very little precise knowledge of the system's design, and cumbersome ray tracing techniques are not used. The method derived uses a mathematical transfer matrix to describe the system as a whole, so individual elements don't have to be modelled. Results from a sample case are presented.!11
