Latest Patents

One of his latest patents is a flexible optical measuring device. This device comprises an optical distance measuring module, an optical fiber adapter, and an optical coupling module. The optical distance measuring module includes a light source, an optical receiver, and a computing unit. The optical fiber adapter connects the optical distance measuring module to the optical coupling module. The optical coupling module consists of a first optical fiber, a two-in-one optical coupler, a detector, and a second optical fiber. A measuring beam is emitted from the light source, reaching the detector. The beam then passes through the detector to the object, forming a reflected beam that returns to the detector. This process allows the computing unit to calculate the distance between the object and the detector's terminal.

Another significant patent is an apparatus for detecting the transmittance of a trench on infrared-transmittable material. This trench is located on a wafer, which is obtained after a ditching process. The apparatus enhances the contrast of an image of the wafer, allowing for automated analysis of the trench's transmittance. This innovation improves the accuracy of detecting transmittance defects, ensuring the quality of the wafer.
