Zusammenfassung:PROBLEM TO BE SOLVED: To provide an oscillation visualization element that can visualize oscillation applied to a measurement object.SOLUTION: An oscillation visualization element according to one embodiment of the present disclosure comprises an optical member that has a stationary part having a position relation relative to a measurement object made stationary, and a movable part being movably supported to the stationary part so that acceleration in a prescribed direction is applied to the stationary part, and thereby the position relation relative to the stationary part varies. In accordance with a change in position relation between the stationary part and the movable part, the optical member is configured to vary reflection intensity of light or electromagnetic wave to be reflected in a retroreflective direction. The acceleration is not applied to the stationary part, and in a still state where the position relation between the stationary part and the movable part stays fixed, the position relation between the stationary part and the movable part comes off a position relation for causing a retroreflection.SELECTED DRAWING: Figure 1 【課題】計測対象物に加わった振動を可視化することができる振動可視化素子を提供する。【解決手段】本開示の一態様に係る振動可視化素子は、計測対象物との相対的な位置関係が固定される固定部と、前記固定部に所定方向の加速度が加わることにより、前記固定部との相対的な位置関係が変化するように、前記固定部に可動に支持される可動部と、を有する光学部材を備え、前記光学部材は、前記固定部と前記可動部との位置関係の変化に応じて、再帰性反射方向へ反射する光又は電磁波の反射強度を変化させ、前記固定部に前記加速度が加わっておらず、前記固定部と前記可動部との位置関係が一定である静止状態において、前記固定部と前記可動部との位置関係は、再帰性反射させるための位置関係からずれている。【選択図】図1
