Title: Walter P. Hollinger: Innovator in Fiber Optic Technology
Introduction
Walter P. Hollinger is a notable inventor based in Mahwah, NJ (US), recognized for his contributions to fiber optic technology. He holds a total of 5 patents, showcasing his innovative spirit and technical expertise in the field.
Latest Patents
Hollinger's latest patents include a "Tuned Integrated Optic Modulator on a Fiber Optic Gyroscope." This system is designed to tune out error signals in high-performance fiber optic gyroscopes. It features a compensation network with both active and passive filters, which are essential for canceling out error signals. The system integrates a fiber optic gyroscope connected to an amplifier, signal processor, square wave detector, modulator driver, and the compensation network. The compensation network is strategically placed between the modulator driver and the phase modulator of the fiber optic gyroscope.
Another significant patent is the "Closed Loop Fiber Optic Gyroscope with Reduced Sensitivity to Electronic Drift." This innovation enhances signal processing by incorporating square wave phase modulation into the modulation drive signal after overflow logic. This arrangement prevents the phase modulation ramp from exceeding overflow/underflow logic limits. The design ensures that phase modulation causes a retrace with each modulation period, maintaining the amplitude of the ramp within predetermined limits. A variable time constant in the retrace correction loop improves performance during the gyro's warm-up period. The amplitude of the gyro's square wave output is determined by analyzing the difference between the output of the first half cycle of the square wave modulation and the average of adjacent second half cycles. This method effectively reduces gyro sensitivity to electronic drift.
