Abstract
A motion analysis tool for viewing the repetitive motion of an object having a video camera for producing images of the object as it moves, a strobe directed at the object for illuminating the object while the image is taken, a controller for capturing a series of video images over a number of cycles of the object wherein only one image is captured in a cycle and each successive image is advanced a predetermined step of time in successive cycle so that when the series of images is displayed a slow motion view of the object is provided while the object moves in the repetitive motion. The analysis tool provides a viewing window wherein the full cycle or only a selected portion of the cycle can be repeatedly viewed. The predetermined steps of time can be varied to increase the resolution.
