Abstract

When a mirror is produced by numerically controlled diamond turning, its surface may be optically smooth except for a sinusoidal height modulation in the radial direction. If the amplitude of the modulation is small compared with its wavelength and the mirror has no aberrations, the reflected light will be a converging spherical wavefront with a radial, sinusoidal modulation superimposed on it. To determine how such a modulation affects the image produced by the mirror we study the reflected light in the focal region.
