The rhino-laryngeal stroboscope system provides professional voice users with a convenient and powerful means of examining laryngeal anatomy and vocal-fold physiology. Both constant and strobe light sources are provided for either general endoscopic viewing (nasal, nasopharyngeal, or laryngeal) or stroboscopic evaluation of the vocal folds during phonation. Both flexible and rigid endoscopes can be used with the system. During stroboscopy the rapidly vibrating vocal folds are illuminated with brief pulses of light. By detecting the pitch (fundamental frequency) of the vocal folds, the timing of these flashes can be regulated through electronic circuitry to produce an image of the vocal folds vibrating slowly to permit detailed observation of vocal fold movement, or "standing still" at various positions within the vibratory cycle. It is important to understand that the image viewed during the stroboscopic exam is not a continuous glottal cycle but a "fusion" of portions of successive cycles. By using stroboscopy, important dynamic aspects of phonations can be viewed clearly.
