We designed and developed a laser line-triangulation endoscope compatible with any standard high-speed camera for a complete three-dimensional profiling of human vocal fold vibration dynamics. With this novel device we are able to measure absolute values of vertical and horizontal vibration amplitudes, length and width of vocal folds as well as the opening and closing velocities from a single in vivo measurement. We have studied, for the first time, the generation and propagation of mucosal waves by locating the position of its maximum vertical position and the propagation velocity. Precise knowledge about the absolute dimensions of human vocal folds and their vibration parameters has significant importance in clinical diagnosis and treatment as well as in fundamental research in voice. The new device can be used to investigate different kinds of pathological conditions including periodic or aperiodic vibrations. Consequently, the new device has significant importance in investigating vocal fold paralysis and in phonosurgical applications.
我们设计并开发了一种与任何标准高速相机兼容的激光线三角测量内窥镜，用于对人类声带振动动力学进行完整的三维轮廓分析。借助这种新型设备，我们能够通过单次体内测量来测量垂直和水平振动幅度的绝对值、声带的长度和宽度以及开合速度。我们首次通过确定黏膜波最大垂直位置的位置和传播速度，研究了黏膜波的产生和传播。关于人类声带的绝对尺寸及其振动参数的精确知识在临床诊断和治疗以及语音基础研究中具有重要意义。这种新设备可用于研究包括周期性或非周期性振动在内的各种病理状况。因此，这种新设备在研究声带麻痹和在嗓音外科应用中具有重要意义。
