Abstract

A motion analyzer is used to capture and store high-speed images. Once the images are stored they may be reviewed in slow motion while quantitative measurements can be made for analysis. New techniques for capturing images are now available in a high speed motion analyzer. These new image capturing techniques have opened the technology door for new opportunities and allows the use of motion analysis in ways not feasible before. Current motion analysis design philosophy uses magnetic tape as the storage medium for recording images. The advantages of this medium high density and non-volatility have been used in the SP2000 Motion Analysis System and KODAK EKTAPRO 1000 Motion Analyzer. Based on industrial experience with motion analysis new image capturing techniques have been developed. These new image capturing techniques are well suited for imaging repetitive processes continuous flow processes controlled events uncontrolled events and varying demand events. An important part of these new image capturing techniques is electronic triggering. The electronic trigger is used to detect a physical phenomena unique to the event to be recorded. The phenomena that sets the trigger can be as simple as a flash switch closure sound temperature or a voltage change. Trigger requirements are application specific. Determining the trigger requirements will require innovation and creativity by the user of the motion analyzer. Given a set of detectors and the hardware for interfacing their outputs the user need to determine the setup to detect the phenomena unique to the event recorded. This paper will address the new image capturing techniques and their application to high speed motion analysis. 2 / SPIE Vol. 1346 Ultrahigh- and High-Speed Photography Videography Photonics and Velocimetry ''90
