Paper Abstract
A noncontact method of monitoring structural displacement is demonstrated. The technique uses a lightweight diffraction grating with a variable period that is attached to the structure of interest. The position of the grating is monitored optically and linear displacement information can be separated from the effects of simultaneous rotary displacement. The technique is demonstrated for both static and dynamic measurements.
