What is Stroboscope and Working Principal of Stroboscope
A stroboscope is an optical instrument used to observe and analyze the motion of objects that are moving at high speeds. It creates an illusion of slowing down or freezing fast-moving processes by emitting short bursts of intense light at specific intervals. This phenomenon takes advantage of the human eye's persistence of vision, where an image remains on the retina for a brief moment after the light source is removed.
Stroboscopes find applications in various industries, including manufacturing, research, entertainment, and more. They enable the visualization of rapid motion that is otherwise difficult to perceive with the naked eye.
Working Principle of Stroboscope
At its core, the working principle of a stroboscope is based on the concept of the "persistence of vision." This phenomenon occurs because the human eye retains an image for a short duration after the light source disappears. A stroboscope exploits this phenomenon by emitting short bursts of intense light at precise intervals. When the flash frequency matches the frequency of a moving object, the object appears stationary or moving in slow motion to the observer.
