Latest Patents

One of Goto's latest inventions is a beam irradiation device. This device utilizes laser beams emitted from a semiconductor laser, which impinge on an irradiation lens supported by a lens actuator. The innovative design allows the laser beams to change their outgoing angle in the y-z plane as the lens actuator is driven, enabling a precise scan of the target region. Additionally, a part of the laser beams is reflected and separated by a beam splitter, converging on a position-sensitive detector (PSD) through a converging lens. A digital signal processing (DSP) control circuit monitors the scan position and adjusts the actuator driving circuit to maintain the irradiation position on the scan trajectory. This design ensures a smooth and stable beam scan operation with a simple construction.

Another notable patent is related to a display device that incorporates a light guide plate. In this device, light incident on the light guide plate from a linear light source is reflected by the prism's reflecting surfaces and emitted from the lower surface of the plate. The emitted light is directed onto a liquid crystal panel, where it is reflected by a layer within the panel and advances toward the screen's front. The light guide plate features minute triangular protrusions on its lower surface, which cover the entire effective area, providing an antireflection effect.
