Title: Innovations of Yaomin Lin in Surface Profile Measurement
Introduction
Yaomin Lin is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of surface profile measurement, holding a total of 5 patents. His work focuses on advanced methods and apparatuses that enhance the accuracy and efficiency of surface profile detection.
Latest Patents
One of his latest patents is a surface profile measuring method that utilizes a broad bandwidth light source. This method illuminates both a sample surface and a reference surface through a splitter. By adjusting the distance between these surfaces in a controlled manner, an interference diagram is generated, depicting the relationship between surface height and illumination intensity. The process begins by selecting the first data point with the highest illumination intensity from the interference data points. Subsequently, a second data point is chosen from a predetermined range around the first data point to ensure optimal waveform symmetry. The peak of a fringe is then estimated using a phase compensating approach.
Another significant patent is an interferometric apparatus and method for surface profile detection. This apparatus includes a light source, a beam splitter, a reflective component, a sensor, and a computing device. The light source emits a beam that is divided into reference and probing beams by the beam splitter. The reflective component is designed so that the reflected reference beam travels different optical path lengths before returning to the beam splitter. The probing beam reflects off the test object and is combined with the reference beam to create a heterodyne light beam. The sensor converts this light beam into an electrical signal, which is recorded by the computing device.
