Abstract : A plan of investigation is outlined by which testing methods could be developed for predicting the suitability of fused quartz blanks for high-performance, folded delay lines. A theoretical basis is derived for the use of the resonant frequency of free, flexural vibration to determine the elastic constants of fused quartz discs. The flexural vibration setup is described and the results are tabulated. Several ultrasonic and optical testing methods are also described. Results of these tests on 38 sample delay line blanks are also given. Plans for proving out the testing methods are outlined. These include the fabrication of delay lines from the sa es and correlation of measured delay line parameters with the results from the various testing methods. (Author)
