Abstract
A method and apparatus is provided for writing a code on an optical element, wherein the code is written on the optical element in the form of a holographic image of an n-dimensional code generated by an interference pattern between a reference beam and a signal beam reflected off a spatial light modulation device having the n-dimensional code configured thereon. The method includes steps of generating the interference pattern between the reference beam and the signal beam reflected off the spatial light modulation device having the n-dimensional code thereon; as well as writing the interference pattern on the optical element as a holographic image of the n-dimensional code.

20. An optical arrangement for writing a code on or in an optical element, comprises:
-
a light source for providing a reference beam; and
a spatial light modulation device having an n-dimensional code configured thereon that responds to a signal beam, for providing a spatial light modulation signal containing the n-dimensional code, the spatial light modulator and the light source being arranged in relation to the optical element so that an interference pattern generated between the spatial light modulation signal and the reference beam is written on or in the optical element as the holographic image of the n-dimensional code. - View Dependent Claims (17, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
