Which type of endoscopy uses a strobe light to capture images?

Stroboscopy is a specialized technique that utilizes a strobe light to capture images of vocal fold vibration at specific intervals. The strobe light flashes at a rate that allows for slow-motion viewing of rapid events, such as the oscillation of vocal folds during phonation. This method enables clinicians and researchers to visualize and analyze the vibratory patterns and health of the voice-producing structures in a detailed manner.

The use of stroboscopy is essential in fields like speech-language pathology and otolaryngology, as it provides valuable insights into issues such as vocal fold pathology or coordination problems. By flashing light at controlled intervals, practitioners can perceive motion that is otherwise too fast to see, which can aid in accurate diagnosis and treatment planning.

Other methods mentioned, such as high-speed cameras and cinematography, while they may involve recording motion, do not specifically employ strobe lighting to capture periodic events in a way that analyzes the rapid oscillations of vocal folds effectively. Laryngeal mirrors, on the other hand, are used for direct visual examination of the larynx but do not provide the same detailed dynamic view that stroboscopy offers.
