Title: Sangtae Park: Innovator in Optical Code Reading Technology
Introduction
Sangtae Park is a notable inventor based in Simi Valley, CA (US). He holds a total of 4 patents that showcase his contributions to the field of optical technology and micro-electromechanical systems (MEMS). His innovative work has significantly advanced the capabilities of optical code readers and MEMS devices.
Latest Patents
One of Sangtae Park's latest patents is a method and apparatus for optical code reading using a MEM optical. This optical code reader features an integrated optical resonator housed within a compact design. The device includes a substrate, a cantilever beam, and a bimorph actuator. The cantilever beam is affixed at one end to the substrate, with a reflective transmit surface on one side and a photodetector on the opposite side. The bimorph actuator responds to electrical stimuli, causing the cantilever beam to move and dynamically alter the field of view of the photodetector. This innovative design allows for a high signal-to-noise ratio, resulting in superior operating characteristics such as long read range and large depths of field. Additionally, the code reader is structurally reliable, low-cost, and energy-efficient, utilizing minimal discrete components.
Another significant patent involves a method of fabricating suspended single crystal silicon micro electro-mechanical systems (MEMS). This method employs a master/slave structure where the motion of a signal device is controlled by a mechanical coupler linked to a control device. The fabrication process utilizes a backside dry etch technique to release the suspended MEMS devices and the mechanical coupler.
