Hunt, Nickel, and Gigault1 concluded their paper on anamorphic images with a brief discussion of the ambiguous location of an image in a convex cylindrical mirror. They also made some observations of the effects of this ambiguity on viewing the image. In a recent paper2 we explored the same ambiguity for a concave cylindrical mirror and the resulting peculiarities associated with viewing. We draw on that work to clarify the nature of the convex cylindrical mirror’s image and to explain some observations of anamorphic images.

For simplicity, consider a point object reflected from a convex cylindrical mirror with its axis vertical. As illustrated in Fig. 1, the rays reflected from a linear, vertical cross section project to point a, while those reflected from a curved, horizontal cross section project to point b. To understand the nature of the reflection from the entire mirror,...
