摘要：

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, am 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.
