Title: Chien Hung Yeh: Innovator in Polarization Conversion Technology
Introduction
Chien Hung Yeh is a prominent inventor based in Taichung, Taiwan. He has made significant contributions to the field of polarization conversion technology, holding a total of 3 patents. His innovative work focuses on methods and apparatuses that enhance the functionality of optical components.
Latest Patents
Chien Hung Yeh's latest patents include a radial polarization conversion component and an azimuthal polarization conversion component, along with their manufacturing methods. The method for manufacturing these components involves placing a holographic recording material between two right-angle prisms. This material is divided into at least four sector-shaped areas, with only one area exposed at a time. A recording light passes through the prisms and the exposed area, interfering with a reflected object light on the holographic recording material. The process includes rotating the material to expose the other areas sequentially, allowing for the construction of volume holograms with diffraction angles of 48.19 degrees, 60 degrees, or about 85 degrees. Additionally, his apparatus for manufacturing these components features a truncated cone-shaped reflector that optimizes light beam exposure and refraction.
