| Research Abstract |
It has been so difficult to provide highly precise gratings required for conventional digital encoders. In this study, no process above is needed because displacement measurement is based on periodic surface acoustic waves (SAWs) generated on a surface of measured object. SAW devices consisting of a piezoelectric substrate and interdigital electrodes were fabricated both for generating and for receiving the SAW with a wavelength of 0.16 mm. Moreover, it was confirmed to detect the SAW propagated along a glass substrate by measuring delay time.
