Abstract: PURPOSE:To arrange so that the transient phenomenon of a light signal by a chopper may not be indicated on a cathode-ray tube by making a signal corresponding to a transient period during an intermittent transmission of a light signal on account of a chopper means and forcibly resetting the sweep action of a time axis control circuit. CONSTITUTION:A light signal 1 input by means of optical fiber, etc. is intermitted by means of a chopper of a light signal input device 2 and then is converted to an electric signal 15 with the help of a light-receiving element. This electric signal is controlled by a time axis control circuit 6 and is indicated on a cathode-ray tube 10. A synchronous signal of the chopper is detected by a control circuit 5 and is shaped in wave form to make a synchronous signal.
