Distant Measurement System and Method of Distant Measurement Using the Same

摘要

A distance measurement system is provided. The distance measurement system includes a femtosecond laser for generating a femtosecond laser beam, a beam transmission unit including three or more optical fibers for irradiating a femtosecond laser beam to a measurement object, a plurality of optical fibers connected to the femtosecond laser, And a composite wave interferometer that is connected between the femtosecond laser and the switching element by an optical fiber and transmits a femtosecond laser beam to the switching element and receives a reflected signal, . The composite wave interferometer includes first and second photodiodes connected by optical fibers to a 2x2 optical coupler and a 2x2 optical coupler.
