Title: James Edward Goodwin: Innovator in Fiber Optic Technology

Introduction

James Edward Goodwin is a notable inventor based in Ramsey, NJ (US). He has made significant contributions to the field of fiber optic technology, holding 2 patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of Goodwin's latest patents is an open loop fiber optic gyroscope designed for measuring ultra-high rates of rotation. This gyroscope incorporates a light source that generates a light beam, which is then processed through a bidirectional coupler. The coupler forwards the light beam to a splitter, which divides it into a first beam and a second beam. These beams are received by a fiber optic coil, where a phase modulator adjusts their phases. A signal processor determines the rotational rate based on the phase difference between the beams. Additionally, if the rotation rate exceeds a certain threshold, a drive circuit activates the phase modulator to make necessary adjustments.

Another significant patent focuses on optical signal noise reduction for fiber optic gyroscopes. This innovation addresses the random intensity noise (RIN) component of the random walk error in fiber optic gyroscopes. By utilizing an unpolarized light signal during processing, Goodwin's method achieves a 3 dB reduction in RIN. This is accomplished by depolarizing the light wave modulated by the fiber optic sensing coil or by combining it with an unmodulated light wave of orthogonal polarization.
