| Conic aspheres can also be tested with spherical wavefronts at their conic conjugate points. |
| We stroboscopically display the motion of single sperical wavefronts from sources arrayed along y-axis. |
| Aspheric surfaces tend to create wavefronts that beat against one another, the changes in one negating the effects of another. |
| The group of wavefronts is called a spectral decomposition wave of the ultrashort pulse. |
| The Shack cube interferometer is used to test converging wavefronts at the center of curvature of a reflective surface. |
