It is well known method that an exposure timer is examined with a spinning top and it also well known fact that we can find some density distribution on its strobo patterns, respectively. The authors have developed a strobo scope which has property of a constant rotating speed with a synchronous motor, and analyze the strobo patterns comparing with oscillograms of X-ray tube voltage waveforms and fluorescence intensity waveforms taken simultaneously with the strobograms. X-ray atrobo scope; ^*1 & 0.5 mm lead slit, thickness 4 mm. ^*8×10 rotating cassette coupled with a synchronous motor. ^*180 RPM constant rotating speed. Result; It can be aproved that the strobo pattern shows following high-tension phenomena, 1. Normal or abnormal pull in, pull out phase. 2. Sarge voltage, being or not. 3. X-ray intensity change during an exposure. 4. X-ray tube voltage waveform distortion. 5. Other abnormalities of X-ray generators. By means of this equipment, one working for a radiological department, can know easily such high-tension phenomena as surge voltage, X-ray intensity change and X-ray tube trouble etc which occur during an exposure, without any high-tension technique at all. It can contribute to a short time exposure technique such as 1 millisecond〜100 milliseconds.
