Abstract:
A diffractive security device is disclosed, including first and second diffractive structures defined in a carrier layer. The first diffractive structure is a diffractive zone plate structure of a continuously curved surface configured such that when the device is illuminated by on-axis light, a first diffraction pattern generated by the first diffractive structure can be viewed from at least a first side of the device at substantially all viewing angles, the first diffraction pattern exhibiting a reference point or reference line relative to which other features of the first diffraction pattern appear to move when the viewing angle is changed. The second diffractive structure is an off-axis diffractive structure configured such that when the device is illuminated by on-axis light a second diffraction pattern generated by the second diffractive structure can be viewed from at least the first side of the device at at least some off-axis viewing angles.

Claim (Index 80):
A method of making a diffractive security device according to  claim 76 , wherein the surface relief is created in a recording medium layer by digitally combining a first surface relief structure corresponding to the first diffractive structure and a second surface relief structure corresponding to the second diffractive structure such that in the second regions of the device the first surface relief structure is modified or destroyed and forming the surface of the recording medium layer in accordance with the combined surface relief.
