1、 Introduction to Resonance Analyzer:

Real time visualization of resonance analyzer and slow motion recording of vibration and rotation; For example, on electric vibration tables, engine test benches, hard to access locations, or miniature objects. StrobeCAM is a user-friendly alternative solution for high-speed cameras, which increases many possibilities.The slow motion visualization speed is user adjustable and constant for all input frequencies. Therefore, the human eye can easily recognize the motion of objects. Through this innovative principle, it is possible to5Hzto2kHzClearly display the motion of objects within the entire frequency scanning range.

2、 Main features of resonance analyzer:

Real time slow motion visualization of rapid periodic events

Record and comment on video and image sequences for recording purposes

Simple and intuitive system usage

An integrated viewer for recording videos (AVI)

Constant LED light - no strobe light

Optional software for image analysis: LIMtrack for measuring motion and resonance curves

Spatial resolution measurement of 3D displacement and deformation (simulated form) .

3、 Main technical specifications of resonance analyzer:

Frequency range: 1Hz~60Khz

Camera pixels: 0.3 MPixel to 29 MPixel Color or monochrome

Signal:COLA signal from 0,5V amplitude

Configuration: camera, lens, trigger unitLEDLampStrobeCAMSoftware, etc.

4、 Example of Resonance Analyzer:

Assuming the camera can record the maximum30HzThe image has a vibration frequency of100HzThen, the triggering system will generate a triggering signal every third cycle of the input signal. The following figure shows the timeline:

In a phase that varies over time（=“phase scanning”）When triggered, the motion of the object is displayed in slow motion. Scanning frequency (e.g1Within seconds360°）Defined slow motion visualization speed.

The software displays the slow motion of the spring throughout the entire frequency scanning process.This figure shows the level of markers measured based on excitation frequency（U） And vertically （V） motion.
