ABSTRACT:
Light emission to be observed is repeatedly started by starting means when each timing interval is maintained much longer than the sustaining time of the light emission. An image initiated by the starting means is incident on the photoelectric plate of an electron beam shutter tube when produced by imaging means. Sampling interval specifying means specifies different sampling interval for each occurrence of light emission if it detects the start of the starting means. Sutter tube driving means cuts the shuttering electric field during the sampling interval. Brightness on the phosphor screen due to an electronic image emitted during the sampling interval is converted into the corresponding electric signal by a photoelectric converter opposed to the phosphor screen of the shutter tube. The output signal of the photoelectric converter is stored in a memory device through a transferring means, and the contents of the memory device are displayed on displaying means or outputtted by an output device.
