Latest Patents
Choi's latest patents include an innovative optical pickup and a wedge beam splitter. The optical pickup for a recording medium features a light source, an objective lens, a main photodetector, and a front photodetector. This configuration allows for the effective convergence or divergence of light on a plate beam splitter, ensuring that light is received at an effective light receiving region of the front photodetector without interference from internal reflections. Additionally, the wedge beam splitter includes first and second mirror planes at a predetermined angle, which transmits and reflects incident light at a specific ratio. This design enables the detection of light that is directly proportional to the output power of the light source, enhancing the linearity of the output power.
Another notable patent is a compatible optical pickup device that utilizes a single light source emitting light with a wavelength longer than 650 nm. This device incorporates an objective lens with various lens areas to focus light for different types of optical disks. The optical path changer and photodetector work together to receive and detect information signals from the reflected light.
