Abstract: A vibration visualizer comprising an optical member including a fixed section to be fixed to a measurement object; and a movable section movably supported by the fixed section such that a first positional relationship between the fixed section and the movable section is changed by application of an acceleration to the fixed section in a predetermined direction. The optical member changes a reflection intensity of light or electromagnetic wave reflected in a retroreflection direction according to a change of the first positional relationship. The first positional relationship in a stationary state where the acceleration is not applied to the fixed section and the first positional relationship is maintained constant, is different from the first positional relationship most suitable for retroreflection.
