“…There was a significant delay between the Qswitch, the top trace (shown in Figure 3), and the laser firing recorded with fast photodiode, as shown in the bottom trace in Figure 3. A similar problem concerning the acquiring of the streak image in the time frame of interest was solved by Mohamed and Kadowaki [11] by using an image light scope. To determine the time that a streak image begins relative to the Q-switch trigger signal and the laser pulse, we had to tabulate the important time parameters of the detection system, provided in Table 1.…”

We describe a streak camera system that is capable of both spatial and spectral measurements of laser-induced plasma. The system is based on a Hamamatsu C4334 streak camera and SpectraPro 2300i spectrograph. To improve the analysis of laser-induced plasma development, it is necessary to determine the timing of laser excitation in regard to the time scale on streak images. We present several methods to determine the laser signal timing on streak images—one uses the fast photodiode, and other techniques are based on the inclusion of the laser pulse directly on the streak image. A Nd:YAG laser (λ = 1064 nm, Quantel, Brilliant B) was employed as the excitation source. The problem of synchronization of the streak camera with the Q-switched Nd:YAG laser is also analyzed. A simple modification of the spectrograph enables easy switching between the spectral and spatial measurement modes.

“…The meaning of each notation is stated below the chart. The observation system is shown in figure 3 and is introduced in detail in our previous paper [15]. Once breakdown occurs, breakdown light will pass through 2 path; (1) IGS (Mitsubishi Cables Ltd. RBD45-A2008) and (2) streak camera (Optronis GmBh, SC-10, 2 ps time resolution, <100 µm spatial resolution) triggering system.…”

We observe streak images of dc pre-breakdown in silicone-oil (10 cSt, 100 cSt and 10000 cSt) / low density polyethylene (30 μm in thickness) composite insulation under needle / sphere electrode by using the 20 meter long image guide scope and a streak camera. In the case of composite insulation with 10 cSt of silicone-oil, breakdown light propagates from the needle side under both voltage polarity. However, in the 10000 cSt case, breakdown light propagates from the film side under the negative voltage polarity. The mechanism of these transient phenomena are discussed in this paper.
