Is stroboscope a useful device to control the translational vibrations?
A stroboscope, also known as a strobe, is an instrument used to make a cyclically moving object appear to be slow-moving, or stationary. It consists of either a rotating disk with slots or holes or a lamp such as a flashtube which produces brief repetitive flashes of light. Wikipedia.
A classic example is the stroboscope used to set the timing on a petrol engine. The strobe lamp is triggered by the ignition system and the light pointed at the timing belt pulley which has a mark on it. The effect is to "freeze" the timing mark against the timing scale mounted on the engine block so that you can read the timing angle.
There is few material on net related to stroboscope applications.
I'm sure there are thousands of articles and videos.
Since it is an optical device, it is best used to control the vibrations of rotary devices like turbine blades electromotors etc.
No. It is used for inspection, not control, although it is feasible that a vision system could use the data to correct a process.
But is it also useful if you want to control the vibrations of a lump mass (big and heavy structure) doing very small vibration in its place in very high frequencies?
Have a look at Amplified video motion which will give you some ideas for search terms.
