1. A microscope system for observing and determining the velocity of moving particles, comprising a television camera which includes an image sensitive device, having short term storage capability, and a scan system for producing electrical, image-information signals representative of the image sensed by said device, the scan system being adapted to successively scan said device, with blank periods interposed between successive scans, no such signals being produced during the blank periods, and the storage capability of said image-sensitive device being such that an image is stored until said device is scanned and the image is converted to electrical, image-information signals;

  • a light source adapted to produce a series of light pulse pairs, the second pulse of each pair occurring a present time interval after the first pulse of that pair, and each pulse pair having a duration less than the duration of a blank period of the camera;

    means for synchronizing the light source and the camera, so that any light pulse pairs occur during a blank period of the camera;

    magnifying means for focusing the camera on an object plane between the light source and the camera, so that the camera sees a magnified image of anything placed in the object plane; and

    means for monitoring the camera picture to obtain desired information.
