the process of converting a holographic image from photoresist or plastic to metal (nickel). See Shim definition.

Eye-mark (or registration mark)

where some step in the overall manufacturing process requires a machine to process a single holographic image, an eye mark is invariably place next to each image to allow proper registration.

E-Beam (electron beam)

a method of creating a holographic image by ‘writing’ the individual interference fringes using a fine beam of electrons in a vacuum chamber. The challenge here is to calculate the exact position of each fringe according to where it would have resulted if a...
