One of the more advanced concepts is the laser/fiber-optics gyro. For this gyro a fiber-optics cable up to 300 (100 m) in length is coiled many times around a loop, with both ends brought out to a laser. The laser beam is split into two beams, with the beams directed into the opposite ends of the coiled fiber-optics cable. Upon emerging from the opposite ends, they are recombined at the beam splitter to form interference fringes. Unlike the laser gyro, the coiled fiber is not a part of the resonant cavity and hence does not exhibit the lock-in phenomena; however, a rotation rate causes only a fringe displacement and not an integrating effect as in the laser gyro. The instrument is therefore a rate gyro and not a rate-integrating gyro.  1, record 1, English, - coiled%20fiber
