Title: Daichi Sakai: Innovator in Optical Technology
Introduction
Daichi Sakai is a prominent inventor based in Ibaraki, Japan. He has made significant contributions to the field of optical technology, holding a total of six patents. His work focuses on enhancing optical devices, particularly in improving color mixing properties and homogeneity.
Latest Patents
One of Sakai's latest patents is an optical integrator and video projection device. The purpose of this invention is to provide a small optical integrator that enhances color mixing and homogeneity. The optical integrator features a light entrance surface, an exit surface, and side surfaces that connect them. It is filled with a light guide material containing scattering particles that differ in refractive index from the light guide material. This design allows light entering through the entrance surface to propagate towards the exit surface while being scattered by the particles, ultimately guiding part of the scattered light to the exit surface through internal reflection.
Another notable patent is a substrate with a lens and its production method. This invention includes a substrate with a columnar member on one surface and a lens member on the columnar member. By selecting the height of the lens, it can be formed in a uniform and desired shape, reducing the distance between the lens and other optical members.
