摘要： An apparatus and method of determining gyro het phase and acceleration at turnaround using the digitized heterodyne signals. A digital design that incorporates the necessary logic and is integrated into a gyro unit. An integer algorithm that processes the turnaround data to produce a phase correction that can be added to the gyroscope count. Separation of high speed data processing from lower rate data to simplify the code and permit evaluation of turnaround correction performance.

摘要： A sleeve (22) enables attachment of an optic fiber (14) to a multi-integrated optic chip (10) in optical communication therewith, and maintains alignment of the fiber at its end adjacent the chip. The sleeve includes a symmetrically-shaped cavity (26) bounded by termini (30, 32) which are respectively disposed to fit onto the chip and to accept the fiber. An adhesive (46) within the cavity symmetrically bonds the fiber to the chip. The adhesive cures symmetrically in the cavity, to eliminate undesired motion of the fiber from its preferred alignment position vis-a-vis the chip connection point (12) or to provide a repeatable motion to achieve the optimum alignment position of the fiber with respect to the chip. The sleeve may be left in place or, alternatively, it may be removed. The sleeve controls, defines and confines the index matching adhesive and/or fluid between fiber end (44) and connection point (12) by defining the areas and volume actually in contact with the adhesive or fluid. Symmetry is preserved over the effects of gravity and wicking which heretofore have prevented a very symmetrical pigtail which is necessary for performance and repeatability.

摘要： A triaxial gyro system includes a loop controller for generating a multiplexed digital biasing waveform. The controller receives the multiplexed outputs of the three gyros in digital form from an analog-to-digital converter. The loop controller is arranged to generate a digital waveform for multiplexed driving of the phase modulators associated with the three gyros. Within the loop controller, the multiplexed gyro outputs are independently processed in such a way that a biasing waveform is generated which permits sequential driving of the phase modulators without any need for resetting buffer cycles.

摘要： The use of a high speed moving average filter is shown to filter high speed errors, including white noise in angle and quantization errors, from the output data of a ring laser gyro while it is being tested. The filtered data permits investigation of the lower speed, random walk in angle error of the gyro being tested. For best results, several moving average filters are connected in series.

摘要： A phase locked loop is disclosed which subtracts an estimated signal from an input signal and operates upon the residual signal. The residual signal is demodulated and applied to a controlled oscillator which produces feedback signals approximately the sine and cosine of the input signal. The cosine feedback signal is multiplied by the residual signal whose resultant signal is a frequency correction signal. The sine feedback signal is multiplied by the residual signal for multiplication again by the sine feedback signal to produce the estimated signal which is amplitude and frequency controlled. This signal is then subtracted from the input signal to reduce the residual signal to near zero.
