Abstract :
Onboard computers often employ AT-Zit quartz resonators. During the flight the engine produces vibrations in a wide range of frequency. These vibrations are dangerous for the quartz resonators. It is shown that holographic interferometry allows supervising not only normal, but also longitudinal and planimetric fluctuations of the quartz resonators
