Latest Patents
Hiroshi Inoue holds a patent for an "Optical pickup using diffracted light." This invention provides an optical pickup that emits reading light to an optical disc containing stored information. It reads the information by utilizing the 0th order reflected light from the pit and the diffracted light generated on the pit through the diffraction effect. The optical pickup includes a semiconductor laser for generating the reading light, a first photodiode for producing an electric signal corresponding to the intensity of the 0th order reflected light, and a second photodiode for generating a signal related to the intensity of the diffracted light. Additionally, it features a light focusing and guiding device to focus the reading light onto the pit and guide the reflected light to the first photodiode, along with a light guiding device for directing the diffracted light to the second photodiode. An operation device generates an output signal by taking the difference between the first and second electric signals. Hiroshi Inoue has 1 patent to his name.
