摘要
Abstract
In order to solve the problem of frequency drift existed in the light speed measurement of the difference frequency phase method,the system adopts the technology of high frequency phase-locked loop（PLL）,automatic gain control（AGC）,digital phase measurement and coaxial optical system.The stability and measurement precision are greatly improved.In addition,the design is more convenient and accurate for measuring speed of light in the laboratory.关键词
