Researchers report the development of a motion microscope, which detects, amplifies, and quantifies motions in a video sequence and allows visualization of small motions similar to the way an optical microscope allows visualization of small structures; the authors used this technique to observe a diverse range of motions, such as vibrations of the tectorial membrane of the inner ear, resonant vibrations of a bridge, and wave propagation in an elastic metamaterial, all of which are invisible to the naked eye.
