1. A method of making a microstructure member, comprising:
- providing light beams which are emitted from an arrangement of two or more light sources and which are interferable with one another;
superposing the light beams axially without re-imaging to produce equally spaced interference fringes having two-dimensional monotonous periodicity; and
exposing a recording medium to the produced interference fringes with a fixed relative position between the interference fringes and the recording medium.

Abstract
Method for a member having microstructure elements arranged thereon. Three or more coherent beams are projected on a recording material from finite angular directions relative to each other to form a pattern on the recording material. The pattern recorded on the recording material is subjected to a developing treatment to obtain microstructure elements.
