Title: Innovations of James H. Simpson
Introduction
James H. Simpson is a notable inventor based in Katonah, NY (US). He has made significant contributions to the field of technology, holding a total of 2 patents. His work primarily focuses on advanced measurement systems and laser technology.
Latest Patents
One of his latest patents is the "Ring laser gyroscope utilizing phase detector for minimizing beam lock-in." This invention involves two of the three reflecting mirrors in a ring laser gyroscope being equipped with transducers. These transducers allow the mirrors to control the laser path, while the third mirror is partially reflecting to enable some cavity radiation to exit. The radiation includes winking signal components related to laser beam lock-in. By managing the phase difference between these signal components, minimum lock-in can be achieved.
Another significant patent is the "All-angle gradient magnetometer." This device features first and second magnetic resonance cells mounted on a common base and separated by a predetermined distance. Circularly polarized pumping light is passed through the two cells orthogonally, mixed with linearly polarized readout light. Appropriate filters are used at the output of the cells to eliminate the pumping light, allowing the modulated readout light to be detected in a push-pull manner. This feedback modulates the pumping beams and enables the detection of phase differences between the outputs of the separated cells.
