“Stroboscopie”来自西腊字Strepho(转动)和Skopein(记录),由此可知Stroboscopie的意义就是记录周期性的运动。动态镜的首次描述和使用是1829年物理学家Plateau,1852年他第一次用动态镜检查尸体的喉,1878年Oertel首次检查活人的喉。以后经过不断改进直到目前可以拍摄电影和测量声带长度的动态镜。由肺部来的气流在声带下方产生压力,当肺部气流的压力超过声带张力时,声带的韧带 “Stroboscopie” comes from the characters Strepho (rotation) and Skopine (records). It can be seen that the significance of Stroboscopie is to record periodic movements. The first description and use of the dynamic mirror was the physicist Plateau in 1829. In 1852 he first examined the throat of a corpse with a dynamic microscope. In 1878 Oertel first examined the throat of a living human. After continuous improvement until now can take a movie and measure the length of the vocal cord dynamic mirror. The airflow from the lungs creates pressure under the vocal cords. When the pressure in the lungs exceeds the vocal cord tension, the ligaments of the vocal cords
