Title: Innovations of Yukiya Funanami

Introduction

Yukiya Funanami is a notable inventor based in Chiba, Japan. He has made significant contributions to the field of optical technology, holding a total of 4 patents. His work primarily focuses on polarizing optical apparatuses and image projecting systems.

Latest Patents

One of his latest patents is a polarizing type optical apparatus. This invention features a first polarizing element that is strategically placed in the path of an incident luminous flux from a light source. It also includes a second polarizing element that is positioned in the path of the luminous flux reflected from the first element. The first polarizing element is designed to have a p polarized light component transmitting characteristic that is less sensitive to the incident angle compared to the second element. Additionally, the second polarizing element has an s polarized light component transmitting characteristic that also varies less with respect to the incident angle. This design ensures that the luminous flux reflected by the first polarizing element mainly consists of an s polarized light component, while the flux reflected by the second element is a substantially pure s polarized light component.

Another significant patent by Funanami is an image projecting apparatus. This invention includes a light source that emits light, a spatial light modulating element, and an illuminating optical system that directs light from the source to the modulating element. The projecting optical system is responsible for projecting the image of the spatial light modulating element. Notably, either the illuminating or projecting optical system incorporates a telecentric optical system along with a light shielding frame. This setup is crucial for controlling the angular component of the luminous flux emitted, thereby enhancing the quality of the projected image.
