| Description | Perfect imaging with Maxwell's fish eye opens the exciting prospect of passive imaging systems with a resolution no longer limited by the wave nature of light. But it also challenges some of the accepted wisdom of super-resolution imaging and therefore has been subject to controversy and discussion. Here we describe an idea for even simpler perfect-imaging systems based on geometrical optics and prove by experiment that it works. |
