ABSTRACT:
A light signal observation device, which is provided in combination with light receiving means for detecting a light signal, light intermitting means for intercepting or passing therethrough the light signal incident to the light receiving means, amplifying means for amplifying the output from the light receiving means; time base signal generating means for generating a sawtooth wave in synchronism with the light signal and also while the light signal is intercepted and for generating a luminance modulation signal in the period of generation of the sawtooth wave, and display means for displaying an optical signal waveform including a 0 level on the basis of the output signal from the amplifying means and the sawtooth signal and the luminance modulation signal from the time base signal generating means. The light signal observation device of this invention may be constructed as a synchroscope or a sampling oscilloscope.
