Abstract

This paper discusses several problems on the JX-300 intermittent synchronous high-speed camera developed by the Institue of Optics and Electronics (10E), Academia Sinica in 1985. It is shown that when a framing rate is no more than 120 frames/s, a relatively high reliability is obtained resulting from low acceleration of the moving elements, weak intermittent pulldown strength, low frequency vibration, etc. At the time when a framing rate increases to over 200 frames/s, the photographic resolving power, as well as the film running reliability reduce due to the dramatic increase in vibration and pulldown strenth, which is similar to that in the stationary photography. It is getting worse when the framing rate is up to 300 frames/s. Therefore, deliberating on the choice of a claw mechanism having a framing rate of over 300 frames/s and conducting a series of technical measures are particularly important for a camera to obtain a sharp object image securely, otherwise it can hardly reach the framing rate of 300 frames/s for an intermittent camera. Even if this framing rate is attained, the image quality is also deformed and the mechanism would be rapidly worn off from high vibration.
