- Abstract
- A Mark II fiber optics image dissection camera has been built. It is in general principles similar to the Mark I camera described by J. S. Courtney-Pratt at the Fifth International Congress on High-Speed Photography, but it is larger, faster and more versatile. It has been used to take sequences of pictures at rates up to 100,000/sec using visible light, and at rates of a few thousand per second using repetitive flash x-rays. It will be possible to record sequences of x-ray pictures at rates as high as for visible light as soon as higher speed flash x-ray equipment is available since suitable fast decay phosphors have been found. There are 1800 fibers in the fiber optics dissecting block and therefore 1800 image elements per picture. Up to 85 pictures could be recorded in a sequence at the maximum rate without double exposure. Methods of unscrambling the composite record have been developed for direct viewing or for taking a series of stills or a motion-picture sequence.
