Title: Ke-Xun Sun: Innovator in Charge Management and Angular Sensing
Introduction
Ke-Xun Sun is a prominent inventor based in Stanford, CA (US). He has made significant contributions to the fields of charge management and angular sensing. With a total of 3 patents, his work continues to influence technological advancements.
Latest Patents
One of his latest patents is titled "Charge management of electrically isolated objects via modulated photoelectric charge transfer." This invention involves the transfer of charge to or from an electrically isolated test body through AC modulation of the photoelectric effect. A reference body is positioned near the test body without any physical contact. The facing surfaces of both bodies are illuminated by optical radiation, which causes charged particles to be emitted. An electrical bias is established between the two bodies, and both the optical radiation and electrical bias are modulated at the same frequency. The charge transfer rate is controlled by selecting a phase relation between the optical radiation and the electrical bias.
Another notable patent is the "Grating angle magnification enhanced angular sensor and scanner." This invention exploits the angular magnification effect of diffraction to improve sensing and scanning capabilities. The design focuses on configurations that utilize normal or near-normal incidence angles combined with grazing diffraction angles. This approach enhances angular sensitivity, allowing for better distinction between rotation and vertical displacement. The system can incorporate an interferometer and quad cell detectors to provide sensitivity to various angular displacements.
