Applications:

This is used to provide image of single, two or multiple stillness for the vibrating object, rapidly rolling or a periodic motion object and can also observe movement tracks. Machine parts and vibrating string are common examples.

Measuring Principle:

This instrument consists of a flashtube which produces brief repetitive flashes of light. Usually the rate of the stroboscope is adjustable to different frequencies. When a rotating or vibrating object is observed with the stroboscope at its vibration frequency (or a sub-multiple of it), it appears stationary. Thus, stroboscopes are also used to measure frequency.
