| Abstract: | Light speed is measured by light-modulation method,i.e.the wave of amplitude modulation is created by modulating ligh directly,subsequently,the phase contrast is measured in the light of beat frequency indication,the wave length is measured according to phase change,thus the light speed is obtained and then the error is analyzed.This essay put forward a developed method which would obviously minish error. |

| Keywords: | light speed modulate beat frequency digital |
