Abstract |
The optical frequency of an optical frequency comb can be expressed in terms of frequencies in the microwave band and is called a measure of light. Optical frequency comb devices are expensive laser transmitters, and they are difficult to conduct research using commercially available products. In this study, we measured distances using a low-cost optical frequency comb device and quantitatively evaluated the error. To measure the phase difference, we adjusted the electrical signal using a frequency doubler, double-balanced mixer, and preamplifier. Keywords - Measurement, Frequency Comb, Repetition frequency. | |||||||||
