Fiber gyro with squeezed radiation
نویسنده
چکیده
Received December 11, 1990; revised manuscript received April 30, 1991 A pulse-excited Sagnac fiber interferometer can perform squeezing. If this squeezed radiation is injected into a second Sagnac interferometer that is functioning as a fiber gyro that is itself nonlinear, additional unfavorable squeezing occurs in the gyro. By proper phase adjustment of the injected squeezed radiation it is possible to minimize this effect as long as the Sagnac interferometer that is performing the squeezing has a sufficiently large nonlinearity.

Analysis of Kerr effect in resonator fiber optic gyros with triangular wave phase modulation.
We present an in-depth analysis of the Kerr effect in resonator fiber optic gyros (R-FOGs) based on triangular wave phase modulation. Formulations that relate gyro output to the rotation rate, the Kerr nonlinearity, and other fiber and gyro parameters are derived and used to study the effect of Kerr nonlinearity on the gyro performance. Numerical investigation shows that the Kerr effect results...
متن کاملImproved Attitude Algorithm for Fiber-Optic-Gyro Strapdown INS
Rotation vector algorithm regarded as a classical and conventional attitude algorithm is widely used in strapdown inertial navigation system. This kind of algorithm usually uses incremental angle in calculation processes. However, the output of fiber-optic gyro is angular rate. Integrating angular rate to get incremental angle leads calculation errors. In this paper, a set of improved attitude ...
متن کاملSqueezing in fibers with optical pulses.
A novel method of squeezing with optical pulses in a fiber ring reflector is demonstrated experimentally. Squeezing of greater than 5 +/- 0.3 dB has been observed. The pump is separated from the squeezed radiation with a fiber ring reflector and can be reused, in principle fully, as the local oscillator. The detection is at low frequencies (35-85 kHz) and is unaffected by guided-acoustic-wave B...
متن کاملFiber Optic Gyro for Land Navigation
Requirements for a gyroscope intended for use in land navigation in a coupled dead-reckoning/GPS are governed more by cost than by performance. As a result, explicit performance measures are poorly defined. The development of a low-cost fiber optic gyro for this application is described. Using openloop signal processing, a short coil length, and simple packaging concepts, it represents an evolu...
متن کاملSelf-calibration method based on navigation in high-precision inertial navigation system with fiber optic gyro
A rotary inertial navigation system requires higher calibration accuracy of some error parameters owing to rotation. Conventional multiposition and rotation calibration methods are limited, for they do not consider sensors’ actual operating condition. In order to achieve these parameters’ values as closely as possible to their true values in application, their influence on navigation is analyze...
