Ultrahigh-speed high-repetition shutter camera

An ultra-high speed and high repetition shutter camera with a unique shutter tube has been studied. The shortest shutter time of 14.5 ps, 480 ps, 84 ps, is experimentally obtained at the shutter repetition rate of 1 kHz, 4 MHz, 80 MHz, respectively. Moreover, the camera can be operated in modulation mode using sinusoidal sweep voltage of a few ten volts. Modulation larger than 17% has been obtained at modulation frequency of 4.2 GHz.
