Paper Abstract

This paper concerns a simple and inexpensive method for computing the polychromatic MTF of an optical system whose performance is determined essentially by longitudinal chromatic aberration. This method employs the results of wave optics computation and therefore retains high accuracy regardless of whether image quality is governed primarily by diffraction, geometric aberrations, or any combination thereof. We believe the analysis methods outlined in this paper will provide a useful engineering tool to the systems engineer who wishes some reasonably accurate insight into the effect of chromatic aberration on MTF tradeoffs. For lenses intended for high-acuity aerial photography, as a general rule, chromatic aberration will seriously limit MTF performance for focal lengths longer than 6 inches.
