Digital imaging of vocal fold vibrations is mainly limited by lighting problems. We present a new technique for high optical resolution of vocal fold vibrations (via indirect microlaryngoscopy) using a light intensifier camera. Superficial epithelial structures and secretions can be followed during vibrations by means of high magnification. Recordings of up to 2.4 seconds and 6,000 frames per second, combined with simultaneous recording of acoustic and electroglottographic signals, are possible. This technique allows instant slow-motion monitor control and subsequent documentation on a normal video recording system. We also present preliminary findings of typical vocal fold motion patterns.
声带振动的数字成像主要受光照问题限制。我们提出一种利用光增强相机对声带振动进行高光学分辨率成像的新技术（通过间接显微喉镜检查）。在振动过程中，借助高倍放大可以观察到浅表上皮结构和分泌物。可以进行长达2.4秒、每秒6000帧的记录，并同时记录声学和电子声门图信号。该技术允许在普通视频记录系统上进行即时慢动作监控和后续记录。我们还展示了典型声带运动模式的初步研究结果。
