Abstract: We previously reported that the dynamic photo-elastic method was a very effective measuring technique for the stress distribution of vibrating quartz crystal resonators. The existence of a ...

Bulkwave quartz crystal units form the resonant elements of oscillators as well as voltage-controllåed oscillators designed to exhibit excellent long- and short-term frequency stability. The roots for ...

WE have succeeded in applying multiple-beam interference methods to the study of the surface movements of oscillating quartz crystals, and the striking results obtained indicate that this has opened ...
