Latest Patents

Yoshida holds a patent for a "Projection optical system and projector." This invention involves a projection optical system that projects from a first image plane on a reducing side onto a second image plane on a magnifying side. The system includes a first optical system with multiple lenses that form a first intermediate image on one side of the optical axis. This image is created by light incident from the reducing side and is transformed into a second intermediate image closer to the magnifying side. The second optical system features a first reflective surface with positive power, strategically positioned to optimize the projection process. The design also incorporates an intermediate lens, ensuring that the first intermediate image is inclined towards the reducing side as the distance from the optical axis increases.
