Title: Innovations of Sean Michael Christian
Introduction
Sean Michael Christian is an accomplished inventor based in Woodbridge, VA (US). He holds a total of 5 patents that showcase his expertise in the field of optical sensors and measurement technologies. His innovative contributions have significantly advanced the capabilities of pressure measurement and volumetric dilatometry.
Latest Patents
One of his latest patents is a fiber optic sensor system and method for measuring the pressure of media. This invention provides a fiber optic pressure sensor apparatus that includes a light source, a reflective sensor diaphragm, and an optical fiber. The system is designed to deliver a first wavefront of light to the diaphragm, which moves in accordance with pressure changes in a medium. The optical fiber receives a second wavefront of light reflected from the diaphragm, and the interference between these wavefronts creates a modulated optical signal. A spectrometer converts this optical signal into digital values, allowing for precise pressure measurements.
Another notable patent is an apparatus and method for volumetric dilatometry. This invention features a volumetric dilatometer that includes an optical displacement sensor and a novel signal-processing algorithm. The algorithm recovers phase information from a spectral signal, enabling accurate measurements of absolute distance and displacement. The design also incorporates a micro-translation stage for automated positioning of the optical sensor, enhancing the efficiency of the measurement process.
