Abstract: An electron-optical image tube is made capable of providing direct measurement of luminous events having durations as short as one picosecond and with a time resolution in the picosecond range by providing a metallic mesh extraction electrode in close proximity to the photo-cathode of the image tube and connecting this extraction electrode to a source of positive potential of variable voltage. An image tube streak camera incorporating such an image tube provides means whereby the photo-electrons in the image tube are deflected by a pulsed electric field of rapid rise time to produce a streaked record. The image tube is particularly suited for use in the analysis of laser beam pulses.
