- the second surface part 13 is dark gray.
- the overlay function M (x, y) used in the diffraction structure S (x, y) is an asymmetrical function in the direction of the coordinate axis x.
- the spatial frequency F X or F y is in the range from 2.5 lines / mm to 10 lines / mm.
- the points of discontinuity caused by the operation modulo hub H (FIG. 7) are not shown.
- the "anisotropic" matt structure described above with the preferred direction essentially parallel to the coordinate axis x is used as the relief profile R (x, y).
- the incident light 11 (FIG. 5) is therefore mainly fanned out parallel to the coordinate axis y.
- FIG. 9 The optical effect of the security feature 16 in the case of light 11 (perpendicular to the x-y plane) (FIG. 9) is explained on the basis of FIG. 12a. If the security feature 16 lies in the x - y plane, the incident light 1 1 becomes more intense from the
- the light backscattered by the surface parts 13, 14 has the color of the incident light 11 (FIG. 5) and has the same surface brightness in both surface parts 13, 14, so that no contrast between the two surface parts 13, 14 can be seen.
- the incident light 11 (FIG. 5) strikes the security feature 16 at an angle of incidence, which is tilted to the left about the tilt axis 41. Only in the second surface part 13 is the incident light 1 1 (FIG. 5) scattered.
- the surface brightness of the first surface part 14 is orders of magnitude smaller than that of the second surface part 13, so that the first surface part 14 stands out as a dark surface against the bright second surface part 13.
- the security feature 16 is tilted to the right, the surface brightnesses of the two surface parts 13, 14 now being interchanged.
- a plurality of the first surface parts 14, which form a logo, a lettering, etc. could be arranged on the second surface part 13.
- relief images such as those used on coins and medals, are also found as a continuous overlay function M (x, y) in the at least piecewise
- Diffraction structure S (x, y) is used, the relief profile R (x, y) advantageously being an "isotropic" matt structure.
- the observer of the security element 2 in this embodiment receives the impression of a three-dimensional image with a characteristic surface structure.
- the security element 2 is rotated and tilted, the brightness distribution in the image changes in accordance with the expectation of a real relief image, but protruding elements do not cast a shadow.
- all diffraction structures S are limited in their structure height to the value H S t (FIG. 1), as was explained with reference to FIG. 7.
- the relief profiles R (x, y) and overlay functions M (x, y) used in the special designs described above can be combined as desired with other diffraction structures S (x, y).
- the use of the security features 16 described above in the security element 2 has the advantage that the security feature 16 forms an effective barrier against attempts to copy the security element 2 holographically. In a holographic copy, the position shifts or color shifts on the surface of the security feature 16 can only be seen in a changed form.
