English abstract:
The retardation-, current-, and displacement-amplitudes of a Single Crystal Photo-
Elastic Modulator (SCPEM) made of a LiTaO3-crystal with a resonance frequency of 127.16 kHz
is measured with interferometry and the underlying theory verified. It is found that the retardation
amplitude and the current amplitude are exactly linearly correlated. The relation is independent
from the crystal damping and from the excitation voltage. A control of the current is therefore
sufficient to control the crystal retardation.
