A vibrometer system comprises an optical
sensor head and a
controller which provides
power for the measuring
head and processes the
vibration signal.
All Polytec vibrometer
optical heads produce the
same type of output signal.
This signal is decoded in
the controller to achieve
velocity and/ or displacement
information. Linearity,
accuracy, resolution, dynamic
range etc. are determined
strictly by the type
of decoder used.
Realistically, no single
decoder can cover the
immense measurement
range (140 dB) and
bandwidth (> 20 MHz)
which the optics head
provides. This is why
Polytec offers multiple
choice decoder options for
its outstanding OFV-3001
vibrometer controller.
