Absolute distance measurements based on femtosecond lasers have been extensively studied for precision metrology and advanced manufacturing, with the advantages of traceability, high speed, and nanometer precision. However, in previous studies, the dual femtosecond laser ranging system showed limitations such as system complexity, lower integration, dead zone problems in single optical path detection, and high requirements for laser coherence. It is challenging to achieve a high degree of integration and large-scale continuous measurements using femtosecond lasers, ineluctably limiting practical applications in engineering fields...
