Stroboscopy is a specialized endoscopic imaging technique used to visualize the vocal folds (vocal cords) in slow motion. Because the vocal folds vibrate at 100–400 times per second (too fast for the naked eye), a stroboscope uses a flashing light synchronized with the vibration frequency. This creates a series of apparent still images, allowing doctors to see the mucosal wave —the ripple of tissue across the vocal fold surface. stroboscopy sewell
