High Speed Videostrobometer

Visualization and Recording of Vibrations and Rotations in Slow-Motion

The Videostrobometer is used for visualizing and recording of vibrations and rotations in slow-motion – on shaker, test benches, at non-accessible locations (endoscope-use) and on large or micro objects. It is an easy-to-use  turnkey  system  and  provides  a  low  cost  alternative  to  high  speed  cameras.  No  need  for  flash  lights  permits  day  light  use.  It  allows automatic  monitoring  and  provides  a  wide  range  of  analysis  tools.  In combination with our special nanosecond light pulses it can be applied for frequencies up to 100 kHz as well as for high speed rotations.

Automated monitoring and image  analysis  permits  automatic  process  control  of  test  setups  or  in  production via sensitivity to object location or vibration amplitudes or phase.

◎  Sequences or single shots can be recorded and stored digitally.

◎  Magnification of small objects possible via zoom lenses or microscopes

◎  Quantitative evaluation: The images include information for comparison of objects or states. Image processing tools permit quantitative evaluation of vibration amplitudes.

◎  The “observer” (camera) permits reproducible positioning.

◎  The rotating object can be observed at a defined rotation or crank angle for each revolution.

◎           Synchronisation of Vibration and rotation Sensors is possible via analog or TTL input signals from sensors such as accelerometers or inductive sensors.

◎  Basic modal analysis

◎  Inspection of internal combustion engines

◎  Inspection of fan blades

◎  Analysis of gear wheels

◎  Analysis of resonance response of the test unit on a shaker

◎  RPM measurement of rotation machine for diagnostic inspection

◎  Analysis of oscillating or vibrating vehicles or machine parts

Simple system operation with Window based software

◎   No need for flashlights and dark rooms, no eyestrain as the videostrobometer enables the user to work without eyestrain even under daylight.

◎   Image transmission with safety measures can be setup via remote controlled (e. g. engine test stands). Object-observer distance up to 70m (unlimited using glass fibre).

◎   Operation is possible under extreme environmental conditions (e .g. climatic chambers).

◎   The  cameras  can  be  installed  on locations  with  difficult  access  for  the human  eye.  Endoscope accessories for cameras are available.

◎         The videostrobometer is also available as mobile system (PCMCIA or USB) for laptops in combination with Fire-wire cameras
