Title: Ching-Chuan Hsu: Innovator in Laser Power Control Technology
Introduction
Ching-Chuan Hsu is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of laser power control technology, holding a total of 2 patents. His work focuses on enhancing the efficiency and functionality of optical pick-up units (OPUs).
Latest Patents
Hsu's latest patents include a "Laser Power Control Unit and Method for Performing Auto Power Control." This invention provides a laser power control unit designed to manage the laser power of an OPU. The unit features at least one analog-to-digital converter (ADC) that is electrically connected to the OPU, allowing for the conversion of a front photodiode output signal into a digital feedback signal. Additionally, it includes a digital control circuit that generates a power control signal to regulate the laser power of the OPU. The digital control circuit is equipped with a compensation circuit that adjusts the power control signal based on the difference between the digital feedback signal and a digital target feedback signal.
Another significant patent is the "Laser Power Controller and Method for Performing Auto Power Control." This controller is designed to perform auto power control for OPUs. It incorporates a sample/hold circuit that samples and holds a front photodiode output signal to create an analog feedback signal. The ADC then converts this analog feedback signal into a digital format, which is processed by the digital control circuit to generate and output the power control signal to the OPU.
