| Sumario: | The Fourier Optics Approach and the generalized Coddington's equations are combined to analyze the image of a second order patch surrounding a reference object point. For rays in the tangential section, an expression for the second field derivative of the wavefront aberration function in terms of variables which can be computed tracing rays from this point is obtained. This expression enables the calculation up to second order in field coordinates of the wavefront aberration corresponding to any point in the patch. The theoretical results are tested numerically for a photographic objective. |
