Title: The Innovative Contributions of Hidehiro Kugisaki

Introduction

Hidehiro Kugisaki, a distinguished inventor from Omuta, Japan, has made significant strides in the field of optical technology. With a total of three patents to his name, his work focuses on advancements in optical pickups, essential components in the functionality of optical disks.

Latest Patents

Kugisaki's latest patents showcase innovative methodologies for manufacturing integrated optical pickups. One patent details a method where light emitted from a light-emitting element is transmitted through a first beam splitter film with polarization selectivity. This process generates a zero-order diffraction beam along with two first-order diffraction beams. These beams are precisely applied to an optical disk via a condensing element, allowing for effective information recording and reproduction, as well as accurate tracking and focusing.

Another notable patent describes an optical pickup that enhances the diffusion angle conversion of outgoing light. Here, a diffusion angle conversion hologram is positioned between the light-emitting element and the first beam splitter film, specifying the relationship between the incident beam's diffusion angle and the outgoing beam's diffusion angle. This arrangement ensures that the light reaching the condensing element retains an ideal spherical waveform, free from wave aberration, ultimately condensing the image spot on the optical disk to its diffraction limit. This innovation also facilitates the detection of high-quality RF signals, contributing to stable focus error and track signals.
