Curved mirror

A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex (bulging outward) or concave (bulging inward). Most curved mirrors have surfaces that are shaped like part of a sphere, but other shapes are sometimes used in optical devices. The most common non-spherical type are parabolic reflectors, found in optical devices such as reflecting telescopes that need to image distant objects, since spherical mirror systems, like spherical lenses, suffer from spherical aberration. One advantage that mirror optics have over lens optics is that mirrors do not introduce chromatic aberration.

Referring back to anamorphic art, catoptric art can only be created with a cylindrical mirror in order to reflect the distorted image and create the conventional image once again. While actual cylindrical mirrors are hard to come by, I found a pipe at Home Depot that worked for this purpose. So, you can create your own anamorphic art too! funwithdesigns.wordpress.com
