Abstract

A technique has been developed whereby linear displacement can be measured in a non-contact fashion. The method depends upon the properties of diffraction gratings with linear variation of period along their length. The grating is attached to a structure at a point of interest and interrogated via a collimated laser beam. A theoretical analysis of the technique is given and compared with experimental results.
