High speed imaging system

A system for imaging high speed moving objects, for example, using a scanning beam and beam delivery optics with fast signal processing. It can allow for vocal fold imaging at up to or exceeding approximately 1000 frames per second with grayscale resolution as high as about 100 micrometers or higher and up to about a 12.4 mm square or larger viewing area. The invention can provide imaging of vocal fold vibration that correlates completely with a synchronously-acquired acoustic voice signal. This can enable physicians, voice therapists and research scientists to understand the consequences of abnormal laryngeal dynamics, rather than being limited to simply observing the dynamics. Further, the application of laser technology will allow for accurate measurements of dimension. This can objectify examination findings and treatment outcomes measurement, helping to overcome the serious limitations of current perceptual-based judgments.
