NAGASHIMA Digital Laryngeal Strobe LS-H10
The vibrational state of the vocal cords during phonation is invisible in normal light because they vibrate very quickly. This device can emit flashes of light with controlled emission timing. Thus, by using it in combination with an endoscope, the vibration of the vocal cords during phonation can be observed as a slow-motion image or as a still image. The speed of the slow-motion image can be changed, and the phase of the still image can also be changed with an optional extra.
