Sensor opens up noncontact vibration testing
Polytec has developed a laser doppler vibrometer (LDV) which it claims overcomes the usual barriers to online vibration testing of products during the manufacturing process.
In order to set the object into the right light the stroboscope is combined with suitable fibre optic components.
The heart of the stroboscope is an ultra stable pulsed xenon flash lamp whose light output is focused by an elliptical reflector into the fibre optic.
The BVS-II Wotan has a maximum pulse frequency of 200 Hz.
An integrated microprocessor achieves an excellent pulse-to-pulse stability of typically 2.5 % .
The desired intensity can be defined by an analogue signal by the computer interface RS232 or by setting the default value from the control panel.
The colour temperature is about 5000 K.
The triggering is alternatively possible via a TTL signal (5V), SPS (24V) or PAL/CCIR-video signal.
In the burst mode one trigger signal can deliver several pulses.
Additionally it is possible to synchronise several stroboscopes.
In spite of the high speed processes the stroboscope is able to visualize fast dynamic activities without any motion blur.
Areas of application are (eg) monitoring of printing processes and wafer-inspection.
