Abstract
In this system, reflected light from an electro-optic probe is detected by a photodetector, and only a voltage signal of a frequency which is an integral multiple of the fundamental frequency of the output voltage from the photodetector is detected. The frequency characteristics of the output voltage from the photodetector can be measured at a high speed and a high accuracy.
