An iconoscope electro-optical shutter for high-speed photography

The paper describes the application of television techniques to highspeed photography. The system described uses an iconoscope tube in which the photo-emission is controlled by the application of suitable potentials to the collector electrode. The charge image, formed during a chosen interval, is stored on the mosaic and subsequently scanned. Examples of exposures of various duration down to 2 × 10¿5 sec are shown. The mechanisms of spurious image formation during the ¿shutter-closed¿ period are discussed. The performance of the system is compared with that of the Kerr cell.
