Abstract
The replacement of the standard replication technique by gluing the pre-embossed foil grating for the use in moire interferometry is the concern of the article. The manufacturing of the pre-embossed foil diffraction grating is explained. Relations of the influence of the specimen surface profile to the zero interference field are derived. Some measurements of the profile of glued grating are shown including calculated extraneous interference field. Example of moire interferogram is shown using glued foil grating.
