Abstract

An image forming optical system minimizes the effects of ghosts in an image. In one embodiment of the present invention, light is at an intermediate point of the optical system. Introducing light in this manner can result in ghosts being produced in the imaged data or in data being missing from the imaged data, both of which are undesirable conditions. The present invention minimizes ghosting and loss of data by maintaining one or more optical relationships to within set ranges.
