Latest Patents

One of his latest patents is an "Optical recording apparatus using scanning mirror for generating two-dimensional beam." This invention relates to an optical recording apparatus that converts a one-dimensional signal beam into a two-dimensional signal beam using a scanning mirror during the data recording process on a holographic recording medium. This innovation greatly reduces the manufacturing processes required for producing spatial light modulators. The apparatus includes a light generation and radiation means for generating beams and dispersing them in two directions. Additionally, a reference beam radiation means converts the angles of reference beams and radiates them onto a recording medium. The invention also features a one-dimensional signal beam generation means that diffracts and spatially modulates the beams to create a one-dimensional signal beam, which is then radiated. Furthermore, a two-dimensional signal beam radiation means reflects the one-dimensional signal beam in two directions on the same horizontal plane, allowing for the radiation of a two-dimensional signal beam onto the recording medium.

Another significant patent is related to an "Optical pickup including an optical modulator, and an optical apparatus comprising the optical pickup." This invention focuses on an optical pickup that includes an optical modulator for reflecting and diffracting an incident light beam to generate multiple beams. This optical pickup can simultaneously read multiple data bits using these beams, thus enabling prompt processing of optical disk information. The design allows the optical pickup to accommodate various types of optical disk media using light beams of different wavelengths.
