Title: Stanley M. Angel: Fiber-Optic Sensing and Raman Spectroscopy
Introduction
Stanley M. Angel is an inventor associated with Livermore, California. His patent work focuses on fiber-optic instruments for detecting luminescence and identifying molecular species through Raman spectroscopy. The supplied information lists 2 patents and identifies The United States of America as Represented by the United States as an assignee.
Latest Patents
Angel’s listed inventions include fiber-optic apparatus and methods for measuring luminescence, as well as optrode technologies for detecting molecular species.
One invention describes a dual-fiber forward-scattering optrode for Raman spectroscopy. Its two fiber ends face one another across a space for sampling an analyte. One fiber delivers the excitation signal, while the other collects Raman scattering. Collimating microlenses and optical filters help direct the light and reduce unwanted background emissions and excitation-signal interference.
Another invention concerns a fiber-optic optrode for detecting constituents in a fluid. A thin metal coating, such as silver, gold, or copper, enhances Raman signals from molecules adsorbed on its surface. The fiber carries probe light to the sensing region and returns emitted light for analysis, allowing the detection of particular molecular species. In one configuration, the optrode can also serve as a working electrode in an electrochemical cell and detect products of reactions at its surface.
Career Highlights
The listed patents reflect Angel’s work at the intersection of optical sensing, spectroscopy, and analytical instrumentation. His inventions use fiber-optic designs to bring excitation light to a sample and collect signals that can reveal luminescence or molecular composition.
