Title: The Innovations of Jeffrey G. Farrington
Introduction
Jeffrey G. Farrington is a notable inventor based in Bishop's Stortford, GB. He has made significant contributions to the field of optical technology, particularly in the development of gyroscopes. With a total of five patents to his name, Farrington's work has advanced the understanding and application of the Sagnac effect in optical fiber gyroscopes.
Latest Patents
Farrington's latest patents focus on the measurement of rotation rate using the Sagnac effect. One of his innovations involves a Sagnac effect optical fiber gyroscope that utilizes a phase nulling photo detection technique. This technique drives a feedback loop that controls one or more non-reciprocal elements connected in series with the coil. A commutating switch is employed to reverse the direction of propagation of oppositely directed beams of light through the coil and non-reciprocal elements. The null balance is detected by observing the absence of any a.c. component in the photodetector output, effectively removing a source of systematic error caused by drift in optical parameters of unbalanced components. Another patent describes a similar Sagnac effect optical fiber gyroscope, where a commutating switch is placed immediately before the Sagnac coil. This configuration synthesizes the effect of turning the coil upside down, producing an a.c. signal in response to a constant rotation rate and mitigating systematic errors.
