| Sumario: | Based on some properties of the visual caustic test, the author has developed a photographic technique capable of rendering an objective document about the features of concave optical surfaces which are measurable with the visual caustic test. The plates are measured in a machine capable of measuring in two coordinates and are reduced following well known methods. The agreement between the visual and photographic methods is good and improves at high D/F ratios. Drawings of the apparatus are presented along with measurement and reduction sheets and graphs comparing the visual method and photographic technique. The complete paper will be published elsewhere. |
