Abstract:

The development of a system for detection of small transient phase angle changes in quartz crystal units exposed to simulated nuclear weapons environment SPRF is described. The detection of phase angle change will be made by comparing the signal to itself with the reference signal being delayed by 300 micro sec. This is feasible since the period of interest exists for less than 200 micro sec. The transla tion from phase to amplitude takes place in a pair of vector adders any difference in their outputs represents a change in phase. An oscil loscope with a differential amplifier is used for display so that a photographic record can be made. Calibration of the system is accomplished by inserting fixed increments of delay corres ponding to known phase angle changes. Author
