Title: Innovations of Fang Chuan Ho
Introduction
Fang Chuan Ho is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of optical technology, holding a total of 7 patents. His work primarily focuses on enhancing projection systems through innovative optical components.
Latest Patents
One of his latest patents is a color separation beam splitter for projectors. This invention comprises a plurality of prisms connected with each other and three optical interference filters that are formed on the side surfaces of the prisms. The filters include a yellow color reflective dichroic mirror, a red color reflective dichroic mirror, and a blue color reflective dichroic mirror. These filters work together to filter out yellow light and provide three primary color lights with high color purity. Additionally, by reflecting a light beam twice, the number of layers of dichroic mirrors can be reduced, thereby increasing the color purity of the light. Another significant patent is the field sequential dichroic light valve, which utilizes ferro-electric liquid crystal components and multi-layer thin film broadband polarizing beam-splitting devices as an optical switch. This invention boasts a fast time response and a memory function, with a switch frequency larger than 180 Hz and an optical transmittance exceeding 90%. It effectively switches R, G, and B-colored light beams in a time sequence, making it suitable for full-color projection display systems.
