Caption

The outline of the lizard serves as a test object, as well as the conventional test pattern, a section of a so-called Siemens star. The lizard's tail and the converging rays of the Siemens star can be used to measure how well narrow lines will be reproduced in an image. With a diameter of six-thousandths of a millimeter, the entire test object is about the size of a red blood cell. The smallest resolved structure has a width of 46 nanometers.
