Precíziós sebességmérés lézerinterferometrikus módszerrel

Abstract

The measurements were done in one hand by our modernized Michelson type laser interferometric motion analyzer (LIMA) which measures primarily the displacement. The motion of the corner cube reflector of the measuring arm of the LIMA was simultaneously studied by an LDV (Laser Doppler Vibrometer) device, which primarily measures the velocity on the basis of the Doppler effect. The simultaneous analysis of the vibrations of corner cube reflector made possible the comparison of these two methods, and moreover the survey of the possibilities of their applications.
