Abstract
We describe a formalism which allows the transmission properties of os cillating radial collimators to be discussed using the concept of ''vi sibility'' functions. We develop a small angle approximation to the th eory which proves to be valuable in describing typical instrumental si tuations. Independent Monte Carlo (ray-tracing) simulations give very good agreement with analytical results and provide a means for investi gating situations where an analytical treatment would be extremely com plicated.
