Measuring scale factor of atomic spin gyroscope and closed-loop operation

Investigation on Closed-loop Fiber Optic Gyroscope Structure and Operation

In this paper, I reviewed comprehensively the structure and operation of closed-loop IFOGs, Feedback Erbium-doped fiber amplifier (EFDA) FOGs, called FE-FOG. The procedure of finding the Sagnac shift for closed-loop IFOG has been studied. The signal processing in the closed-loop IFOG was simulated using PSCAD software. In the closed-loop IFOG, the phase shift was derived through frequent use of...

Closed-Loop Operation of A tuator Arrays

Closed-Loop Operation of Actuator Arrays

An actuator array performs distributed manipulation where an object being transported and manipulated rests on a large number of stationary supporting actuators. The authors have developed a macroscopic actuator array consisting of many motorized wheels. As opposed to a MEMS array, the analysis requires the explicit modeling of the discreteness in the system, including the set of supports, dist...

Operation of Closed Loop Signal Systems

In recent years, there have been two parallel research paths for developing advanced traffic signal systems. Real-time traffic adaptive system research, supported largely by the United States Department of Transportation (USDOT) and smaller scale closed loop systems developed primarily by traffic signal system vendors. Simulation models have been developed for evaluating USDOT supported project...

Nuclear Spin Gyroscope Based on an Atomic Comagnetometer

0031-9007= We describe a nuclear spin gyroscope based on an alkali-metal –noble-gas comagnetometer. Optically pumped alkali-metal vapor is used to polarize the noble-gas atoms and detect their gyroscopic precession. Spin precession due to magnetic fields as well as their gradients and transients can be cancelled in this arrangement. The sensitivity is enhanced by using a high-density alkali-met...
