Abstract
The invention relates to a method and system for making reflection holograms and, more specifically, for making reflection holograms from a cylindrical surface of a master. Means are provided to direct substantially monochromatic actinic radiation through a recording medium sensitive to such radiation coupled to the cylindrical surface of the master such that the angle of incidence of the radiation on the master is substantially constant.
