stroboscopy

1.BACKGROUND: Various investigative tools, including direct visualization with stroboscopy and indirect observation with glottography, have been widely used for the observation of vocal fold vibration.

摘要背景：许多观察声带工具，包括影像观察喉频闪镜以及间接观察声，均已被广泛运用于声带观察。

2.Methods Video-stroboscopy was used to reveal the laryngeal cavity and dynamic changes of the vocal fold, and sound spectrograph was used to examine audio frequency, pitch and width.

方法用频闪喉镜显示患者喉腔全貌和声带态变化，用声分析检测并记录患者发声频率、音调和音域。
