摘要： In an optical fiber gyroscope, the sensitivity thereof is optimized with a phase bias afforded by utilizing the phase characteristics of an optical branching/coupling unit. Further, the fluctuation of the intensity of a light source and the error and secular change of the phase characteristics of the optical branching/coupling unit are compensated by an electronic circuit. Moreover, an optical fiber loop is located in a heat insulation casing so as not to be affected by an ambient temperature change, thereby to prevent the drift of the optical fiber gyroscope attributed to an temperature change. Thus, the optical fiber gyroscope of high measurement accuracy is provided.

摘要： An interference sensor passes radiation from a source and a polariser to a loop of optical fiber so that radiation beams circulate in opposite directions around the loop and interfere. The loop contains an optical phase modulator which imposes an optical modulator on the radiation beams circulating on the loop. A converter detects the interfering and modulated beams and generates an interference signal which is then processed by an analyser. The interference in the loop is dependent on rotation of the loop and therefore analysis of the interference signal permits that rotation to be measured. In the present invention, the interference signal is (i) sampled at a frequency different from that of the optical modulation, or (ii) electronically modulated in the analyser at a frequency different from that of the optical modulation, or (iii) optically modulated in the loop at a second optical modulation frequency. The analysis in the analyser may be in the frequency domain (i.e. consideration being given to the frequency of the interference signal) or in the time domain (i.e. independent of frequency).

摘要： A phase modulated light is propagated through an optical fiber sensing loop, from which a propagated light is obtained. The propagated light is converted to an electric signal, from which a fundamental wave component and even number harmonic wave components of a phase modulating signal for the phase modulated signal are detected. In accordance with the changes of the fundamental and even number harmonic wave components, fault is detected. On the other hand, the electric signal may be integrated to provide an integrated signal. In accordance with the comparison between the integrated signal and a fault reference voltage, the fault may be detected.

The navigation system comprises a GPS range measuring device, an angular velocity measuring device, a velocity measuring device and an azimuth measuring device, which measure the motion of the mobile object; a GPS range error estimating device, an angular velocity error estimating device, a velocity error estimating device and an azimuth error estimating device, which estimate errors involved in the respectively corresponding measuring devices; and a position calculating device which calculates the position of the mobile object from the outputs of the error estimating devices. The error estimating devices are implemented by Kalman filters and averaging processes. The factors of the errors of the individual measuring devices are assumed, and the outputs thereof are corrected, so that the position of the mobile object can always be determined at a high accuracy without employing any high precision sensor.

摘要： A method and apparatus for developing microcomputer-based systems. A controller model having at least one parameter is simulated and, similarly, a plant model having at least one parameter and controlled by the controller model is simulated. A user interface then has access to the parameters of the controller model and plant model and optionally suspends the execution of the controller model and plant model in response to a trigger event. The user interface determines the status of the controller model parameters and/or plant model parameters at the time of the trigger without altering the controller model parameters or plant model parameters or the program code of the controller model.
