Paper Abstract

As a basis for calculating lens correction curves, the front and rear focal and nodal surfaces are mapped for lenses used in film analysis. The image of a collimated source is read as a function of incident angle using a linear CCD. The front nodal point is used as a camera position and the measured angular variation provides a fine correction td the object distance. The resulting corrections allow accurate spatial locations to be calculated for target objects imaged at the film plane.
