摘　　要：大尺寸装备制造、空间中航天器编队飞行等领域面临大量程、高速、高精度的绝对距离测量需求,传统的干涉相位法与飞行时间法已经无法满足测量需求。随着光频梳的出现,能够利用光频梳在时域及频域中的高分辨特性,将其应用于测距中。双光梳测距在解决了量程扩展问题后,成为了集大尺度、快速测量、高精度于一体的光学测距手段。梳理了光梳测距的发展过程,阐述了双光梳测距发展过程遇到量程扩展、噪声抑制、空气折射率补偿、光源小型化等问题及解决办法,为双光梳测距系统的完善提供理论指导。Large-scale equipment manufacturing,spacecraft formation flying in space,and other fields are facing largerange,high-speed and high-precision absolute distance measurement requirements.The traditional interferometric phase method and time-of-flight method can no longer meet the measurement requirements.With the advent of optical frequency combs,the high-resolution characteristics of the optical frequency combs in the time and frequency domains can be used for ranging.After solving the problem of range expansion,the dual optical comb ranging has become an optical ranging method that integrates large-scale,fast measurement,and high precision.The article describes the development process of optical comb ranging,expounds the problems and solutions encountered in the development process of dual-comb ranging,such as range expansion,noise suppression,air refractive index compensation,and light source miniaturization.It provides theoretical guidance for the improvement of dual optical comb ranging system.
