High speed Videostroboscope

Principle

The Videostroboscope is used for visualization 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-touse 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.

Advantages of Videostroboscope to the classical light Stroboscope

Automated monitoring: Image analysis permits automatic process control of test setups or in
production via sensitivity to object location or vibration amplitudes or phase (please ask for details).

Recording: Sequences or single shots can be recorded and stored digitally. The images or sequences
(avi, jpg etc.) can be further processed and included to presentations. Compared to conventional High
Speed cameras this can be done over a very long period as the image streem is recored to the computer
memory or hard-disks directly. Using solid state drives (SSD) this is possible with high frame rates an
resolutions e. g. over 200Hz at VGA.

Micro-objects: Applying zoomlenses or microscopes permit magnification of small objects.

Quantitative evaluation: The images include information for comparison of objects or states. Image processing tools such as automated edge detection or correlation and
measurement tools permit quantitative evaluation of vibration amplitudes. No need for dark rooms, no eyestrain: In opposite to conventional systems based on flash lights,
the video-stroboscope enables the user to work without eyestrain e. g. under daylight. High power flash lights are harmful for the eyes allowing short application periods only.

Security and image transmission: The observer can be spatial separated from the object or danger zone by remote controlled versions (e. g. engine test stands). Object-observer distance up to 70m (unlimited using glass fibre).

Environmental: Operation is possible under extreme conditions (e .g. climatic chambers).

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