Title: Hiromitsu Takenaka: Innovator in Spatial Light Modulation Technology
Introduction
Hiromitsu Takenaka is a prominent inventor based in Yokosuka, Japan. He has made significant contributions to the field of spatial light modulation, holding a total of 6 patents. His work focuses on enhancing the performance and efficiency of light modulation devices.
Latest Patents
Among his latest patents is a spatial light modulation device that includes a pixel electrode layer. This device is composed of a photoconductive layer, a dielectric reflection layer, and a liquid crystal layer, all laminated in sequence between first and second drive electrode layers. The pixel electrode layer features a plurality of pixel electrodes that are partitioned by an insulating substance layer and arranged at predetermined intervals. To achieve higher contrast and resolution, the surface area of each pixel electrode on the photoconductive layer side is smaller than that on the dielectric reflection layer side. This innovative design allows for improved modulation and reflection of light.
Another notable patent is a spatial light modulator that utilizes a photoconductive member made of hydrogenated amorphous silicon doped with boron. This modulator is capable of displaying high-resolution moving pictures without an after-image effect. It comprises a pair of transparent electrodes and a photoconductive member interposed between them. The thickness of the photoconductive member is carefully selected to enhance light absorptance, ensuring optimal performance.
