“…In clinical practice, the integration of multi-modalities for vocal fold evaluation would be an innovation that could make laryngoscopic examinations more time-efficient for physicians and more comfortable for patients. However, laryngeal videostroboscopy uses a special light source which flashes and flickers [17,18]. It is likely that the light source of stroboscopy is a big technological obstacle when being integrated with other modalities.…”

Background and Objectives Most laryngeal imaging modalities used continuous light source. However, videostroboscopy adopted the unique stroboscopic flashing light triggered externally and is consistent with fundamental voice frequencies. If laryngeal stroboscopic effect could be obtained in the field of continuous illumination, it woud be more compatible with conventional video. In this study, we established the mathematical algorithm for stroboscopic effect with continuous light and tried to determine the feasibility of laryngeal stroboscopic effect with conventional laryngoscopy using continuous light in the mechanical model.Materials and Method The mechanical model of fan motor system was used to validate to the present study. Rotational images of the fan motor were captured using conventional laryngoscope with continuous light source.Results On the basis of the mathematical model, the optimal ranges of the frequency for stroboscopic effect were expected as (multiples of sampling rate [S])±(S/5). In the fan motor model, the stroboscopic effects could be confirmed on the basis of the mathematical model using conventional videolaryngoscopy with continuous light source.Conclusion Laryngeal stroboscopic effect with continuous light source might be feasible. The stroboscopic effect with continuous light would be expected to provide greater compatibility to integrate with the other imaging modalities for the vocal folds.
