Title: Manabu Akagi: Innovator in Optical Technology
Introduction
Manabu Akagi is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of optical technology, holding a total of 4 patents. His work primarily focuses on advanced mirror devices used in projection displays and color separation systems.
Latest Patents
One of Akagi's latest patents is a reflection mirror designed for a projection display unit. This innovative mirror displays stereoscopic images through light polarization glasses. It reflects linearly polarized light emitted from a projection source through a polarizing plate toward a screen. The design includes a glass substrate, a metal film, and two dielectric films, each with specific thicknesses and refractive indices. This configuration ensures that the phase difference between p-polarized and s-polarized light remains within a range from -45 degrees to 45 degrees, even as the incident angle varies.
Another notable patent is the separation/synthesis mirror device housed in a liquid-filled environment. This device features four dichroic mirrors arranged in an X-shape within a housing filled with liquid. The refractive index of the liquid is higher than that of the dichroic mirrors, which helps to eliminate double image blurs caused by entrance rays. Additionally, the liquid's refractive index decreases when heated, allowing it to approach the refractive index of glass, enhancing the device's performance.
