    摘要: A step voltage generator for outputting a step voltage from an output terminal. The step voltage generator includes a voltage dividing circuit having a plurality of dividing elements serially connected to each other and disposed between two power sources of different voltage levels for voltage dividing the potential difference between the two power sources. The step generator further includes a switching circuit having a plurality of switch devices serially connected to each other and similarly disposed between the two power sources. The end switch device of the serially connected bunch is connected to the output terminal. A trigger circuit turns on the switch devices sequentially starting with the one closest to the output terminal. A plurality of reverse flow preventive circuits prohibit current through a switch device most recently turned on from flowing through a voltage dividing element previously turned on and which remains on.

    摘要: The pair of vertical deflection electrode plates 13 in the double sweeping streak camera are supplied with a voltage of a sawtooth wave in synchronization with the input optical beam pulses. The other pair of horizontal deflection electrode plates 14 are supplied with a voltage of a stepped wave in synchronization with the sawtooth wave. The deflection electrode plates 13 and 14 sweep successively-incident photoelectrons. The photoelectrons are then detected at the phosphor screen 16. The phosphor screen 16 is therefore recorded with temporal changes in the spatial pattern of the optical beam pulse as an image of regularly-arranged optical beam patterns. The image analyzing device can easily analyze the image.
