The use of videostroboscopic cameras operating at normal speeds (24-30 frames per second or fps) is commonplace in laryngoscopy. However, the time between recorded frames can include several glottal cycles. Thus, only disorders that persist for many tens of cycles can be distinguished. To observe more transient events, a higher frame rate is needed. High-speed (>200 fps) digital cameras provide such an option. These cameras offer good resolution, easy operation, and very fast frame rates (up to 12000 fps) that allow for capture of transitory events, such as onsets and offsets of voicing and the details of a single vibratory cycle. These attributes can prove useful to voice clinicians and researchers alike. This article examines the use of such cameras with and without image intensifiers in a clinical and research setting and offers recommendations for their operation, including the synchronization of the frame information with audio or other data. Specific information is offered on the Kodak EktaPro Hi-Spec Motion Analyzer Model 1012 with Intensified Imager Model VSG.
