Title: Ralph Barry Johnson: Innovator in Electro-Optical Technology
Introduction
Ralph Barry Johnson is a notable inventor based in Huntsville, AL (US). He holds a total of 7 patents, showcasing his contributions to the field of electro-optical technology. His innovative designs and systems have significantly impacted various applications in the industry.
Latest Patents
One of Johnson's latest patents is the "Electro-optical transducer with multi-reflector beam-expanding and collimating input/output device." This invention utilizes a system of reflectors to create beam-expanding and collimating electro-optic transducer devices, which can include radiation sources and/or detectors. The reflector system is preferably of the Cassegrainian or Ritchey-Chretien type. Additionally, light signals can be conducted to or from the transducers using fiber-optic cables. The alignment of optical conductors or 'cores' of the fiber-optic cables or the reflector system with a transducer is achieved by coupling a magnetic member to the conductor or reflector system. A controllable magnetic field is then applied from outside the device to ensure proper alignment, followed by fixing the components in place using methods such as light-curable epoxy resin. Another significant invention is the "Pseudo elliptically-shaped tool," which is designed for creating a mandrel. This tool features a circular-shaped portion that approximates a circular portion of a desired elliptical shape, along with a plurality of facets that are adjacent to the circular-shaped portion, each approximating a portion of the elliptical shape.
