A stroboscopic laryngoscope is a medical device that uses the stroboscopic effect to observe vocal cord vibration. By matching the frequency of synchronized flashes with the vocal cord movement, it creates a "slow-motion" visual effect, allowing for dynamic assessment of vocal cord vibration characteristics and diagnosing laryngeal diseases. Its core principle is the phenomenon of visual persistence, which can accurately capture details such as the opening and closing patterns of the vocal cords and changes in mucosal waves.
Working Principle
1、Stroboscopic Light Source:The device emits short pulses of light synchronized with the frequency of vocal cord vibration. When the flash frequency approaches the vocal cord vibration frequency, the persistence of vision in the human eye "freezes" the high-speed vibration of the vocal cords into a continuous dynamic image.
2、Dynamic Capture:An endoscopic camera records different phases of the vocal cord vibration cycle (such as opening and closing processes, amplitude, and symmetry), generating slow-motion videos that visually display subtle pathological changes (such as vocal cord nodules, polyps, or paralysis).
3、Synchronization Trigger:A laryngeal microphone or air pressure sensor is required to acquire the vocal cord vibration frequency, ensuring that the flashes are synchronized with the vocal cord movement and
