Title: Innovations of Sung-du Kwon
Introduction
Sung-du Kwon is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of optical systems, holding a total of 6 patents. His work primarily focuses on enhancing the efficiency and effectiveness of optical pickup systems.
Latest Patents
One of his latest patents is an "Apparatus for controlling monitor photo diode in optical pickup system." This invention monitors an optical power signal output for writing or reading data from a disk. The apparatus includes a comparator that compares a voltage signal corresponding to the optical power signal output from the laser diode (LD) with a predetermined reference voltage signal. Additionally, it features a gain selector that selectively issues a gain output from the comparator based on the type of optical power signal output from the LD.
Another notable patent is the "Apparatus and method for detecting beam power in optical drive." This invention allows for the detection of beam power generated by multiple light sources using a single device. The apparatus includes a light-receiving unit that captures the beam power from one of the light sources and an amplifying unit that selects a gain, amplifies the received beam power, and outputs the amplified power as detected beam power. This method ensures that the detected beam power considers the dynamic range for each light source, thereby achieving effective automatic power control (APC).
