It is impossible to find the object which is not vibrates. From the oscillation of molecules to periodic vibrating object, our world is filled with large and tiny oscillation. Therefore, it is important to operate and analyze the oscillation. Oscilloscope is a typical instrument for analyzing oscillation, however, it is essential for all oscillation to go through the change to the electromagnetic wave. The aim is to analyze the visible vibrating plate without oscillator however, this instrument is troublesome to use conveniently in our lives, because it is essential for all oscillation to go through the change to the electromagnetic wave. We made the measurement instrument for analyzing the oscillation easily. At this time we connected the idea of Lissajous figure. By this new instrument, we also visualize the occurrence principal of Lissajous figure, and furthermore we could analyze the vibrating phase.
